About Kos

Kos is located in the southeastern Aegean Sea and is part of the Greek Dodecanese islands. Situated just off the Turkish coast, the island offers clear views of the mountains of Turkey on sunny days. This unique location has shaped Kos throughout history, giving it a fascinating blend of Greek charm, rich cultural heritage, and Mediterranean atmosphere.

Many travellers know Kos mainly as a beach destination with large all-inclusive resorts. But once you start exploring the island, you’ll quickly discover a completely different side. You’ll find charming boutique hotels, small-scale accommodations, authentic villages, a rich history, beautiful natural landscapes, and a relaxed island vibe. It’s this combination that makes Kos far more diverse than you might expect at first glance.

What I personally loved most about Kos is how effortlessly it combines relaxation with exploration. In no time, you can drive from the coast into the scenic countryside, stop whenever a beautiful viewpoint catches your eye, and end the day on a cosy terrace enjoying delicious Greek food. Thanks to the island’s compact size, you’ll never spend long on the road, allowing you to experience a surprising amount of Kos in a single holiday.

How to travel to Kos

The easiest way to reach Kos is by plane. During the summer season, several direct flights operate from Belgium, allowing you to arrive on the island in around 3.5 hours. If you’re travelling outside the summer months, you’ll usually fly via Athens, followed by a short domestic flight to Kos.

If you’re planning an island-hopping adventure, taking the ferry is a great option. Regular ferry services connect Kos with several other Greek islands, making it easy to combine multiple destinations in one trip. You can also reach Kos from the Turkish resort town of Bodrum in less than an hour by ferry. Thanks to this short crossing, many travellers choose to combine both Greece and Turkey in a single holiday.

Once you’re on Kos, there are several ways to get around. Renting a car, is the best option if you want to explore every corner of the island. An e-bike is perfect for discovering the area around Kos Town and the coastline, while the electric assistance makes tackling the island’s hilly roads much easier. Looking for a bit more adventure? Renting a buggy is another popular way to explore Kos at your own pace.

Not sure which mode of transport suits your trip best? Or looking for practical advice on renting a car, driving, parking, paying by card, and tipping on Kos? Be sure to check out my blog, “10 Kos travel tips you need to know before you go.”

How many days do you need in Kos?

For a first visit to Kos, I recommend staying for at least five days. This gives you enough time to explore the island’s main attractions while still enjoying a few relaxing afternoons at the beach.

If you have a full week, even better. You’ll be able to discover the island at a leisurely pace, visit charming villages, enjoy scenic drives, and fully experience the delicious Greek cuisine.

I personally spent five days on Kos, and for me, that was the perfect amount of time. I’m not someone who spends entire days relaxing on the beach. Instead, I prefer exploring viewpoints, wandering through picturesque villages, and discovering local hidden gems. If you’re more of a beach lover, however, a week or longer is definitely worth considering.

21 epic things to do in Kos

To help you make the most of your holiday in Kos, I’ve put together a list of the 21 best things to do in and around Kos that you simply shouldn’t miss. To make planning easier, I’ve divided them into three convenient categories: Kos Town, the rest of the island of Kos, and attractions beyond Kos. I’ve also created a handy map showing the location of every attraction, so you can easily see what there is to discover across the island and plan an itinerary that suits your trip.

Things to do in Kos Town:

1 – Wander through the charming Old Town of Kos

The historic centre of Kos Town is without a doubt one of the island’s most charming places to visit. Stroll through its atmospheric streets lined with boutique shops, lively squares, and traditional Greek tavernas. It’s the perfect place to wander without an itinerary and simply soak up the local atmosphere.

Along the way, you’ll come across plenty of lovely souvenir shops. Be sure to take home something typically Greek. Local olive oil, honey, herbs, and handmade ceramics all make wonderful souvenirs. Natural olive oil skincare products, handmade leather sandals, and colourful jewellery are also popular choices.

Afterwards, find a cosy terrace and enjoy a drink or a traditional Greek lunch while watching the world go by. The Old Town becomes especially magical after sunset, when both locals and visitors fill the streets, the terraces come alive, and the relaxed holiday atmosphere that Greece is famous for truly shines.

2 – Stroll along the harbour of Kos Town

The harbour of Kos Town is the lively heart of the city. Throughout the day, it buzzes with a relaxed holiday atmosphere. The waterfront promenade is lined with cafés, restaurants, and colourful fishing boats and sailing yachts, making it the perfect place for a leisurely walk while enjoying the harbour views.

Every day, dozens of boat trips depart from the harbour to nearby Greek islands and the Turkish coast. As a result, it can get quite busy during the summer months, but that lively atmosphere is all part of the harbour’s charm.

Be sure to wander away from the promenade and discover the famous white alley. With its whitewashed houses, colourful flowers, and unmistakable Greek charm, it’s one of the most photogenic spots in Kos Town. It’s the perfect place to escape the crowds for a moment while capturing some beautiful photos.

3 – Visit the Plane Tree of Hippocrates

The Plane Tree of Hippocrates is undoubtedly one of the most iconic landmarks in Kos. According to legend, Hippocrates, the father of modern medicine, taught his students beneath this very tree. Although the current tree is much younger than the original, it remains a fascinating historical site and an important symbol of the island.

Plane Tree of Hippocrates, Kos Town, Kos, Greece

The tree is located just a short walk from the harbour, making it almost impossible to miss while exploring Kos Town. The surrounding square is filled with cafés and historic buildings, making it a pleasant place to take a break. Even if you’re not particularly interested in history, it’s well worth stopping by. Better yet, the Plane Tree of Hippocrates is within walking distance of many other attractions, making it an easy addition to your Kos Town itinerary.

4 – Climb Neratzia Castle for the best views

If you only visit one historical site in Kos Town, make it Neratzia Castle. This impressive fortress was built in the 15th century by the Knights of Saint John to protect the harbour from pirates and invading forces. Today, you can wander through its centuries-old walls, towers, and gateways, all of which remain remarkably well preserved.

What impressed me most were the spectacular views. From the castle walls, you’ll overlook the harbour of Kos, the crystal-clear Aegean Sea, and even the Turkish coastline. That alone made the visit worthwhile. During my visit, admission was only €2.50, making it one of the best-value attractions on the island. Allow around an hour to explore the castle at a relaxed pace and enjoy the many photo opportunities along the way.

5 – Explore the ancient Agora of Kos Town

Right in the heart of Kos Town, you’ll find yourself surrounded by over 2,000 years of history. In ancient times, the Ancient Agora was the city’s bustling commercial and social centre, where people gathered to trade, meet, and discuss important matters. Today, you can wander among impressive columns, ancient foundations, and archaeological remains that offer a glimpse into the grandeur of this once-thriving marketplace.

What I loved most is how seamlessly the ruins blend into the modern town. One moment you’re strolling through lively shopping streets, and the next you’re walking through ancient history. Best of all, admission is free, and you don’t need hours to explore the site. It’s the perfect stop while discovering Kos Town. Take a moment to imagine what life here must have looked like more than two millennia ago.

6 – Visit the Roman Odeon of Kos

The Roman Odeon is one of the best-preserved ancient monuments in Kos Town. Built during the 2nd century AD, this small open-air theatre once hosted musical performances, theatrical productions, and political gatherings. Today, it still provides an excellent impression of what the theatre looked like nearly two thousand years ago.

You can walk between the original stone seating and even sit on the marble benches, making the experience much more immersive than at many other archaeological sites. Beneath the theatre, you’ll also discover a series of vaulted chambers that were once used for storage and other practical purposes.

One of the things I appreciated most was how peaceful the site feels. Despite being close to the town centre, it’s often much quieter than Kos’ other major attractions. Admission is free, making it an easy stop while exploring Kos Town.

7 – Walk through the Ancient Gymnasium

Just a short walk from the Roman Odeon lie the impressive remains of the Ancient Gymnasium. In ancient Greece, a gymnasium was much more than a place for sports. Young men came here not only to train physically but also to study and develop intellectually. It was an important social and educational centre in everyday Greek life.

Today, you can stroll among the remaining columns and foundations while imagining how magnificent this complex must once have been. What stood out to me most was how peaceful it feels. Despite its central location, it’s usually much quieter than many of the island’s other attractions.

Admission is free, and a visit doesn’t take long. I recommend combining the Ancient Gymnasium with the Roman Odeon and the Ancient Agora to discover some of Kos Town’s most important historical landmarks in a single walk.

8 – Relax at Lambi Beach

Fancy a few hours of sun, sea, and relaxation? Lambi Beach is one of the best beaches close to Kos Town. Located within walking or cycling distance of the centre, it’s the perfect place to combine sightseeing with a refreshing swim in the Aegean Sea.

The beachfront is lined with beach bars and restaurants where you can rent a sunbed or enjoy a drink by the sea. One of the most popular spots is Mykonos Beach Club, where you’ll find comfortable loungers, a lively atmosphere, delicious cocktails, and beautiful views over the turquoise water. It’s the perfect place to unwind after a day of exploring.

Things to do in Kos

9 – Visit the impressive Asklepieion

A visit to the Asklepieion is an absolute must during your holiday on Kos. This impressive ancient sanctuary sits on a hillside, about four kilometres from Kos Town. We cycled there by e-bike, and I can highly recommend it. The road gradually climbs uphill, but thanks to the electric assistance, the ride is very manageable.

The Asklepieion was one of the most important healing centres of the ancient world. According to legend, Hippocrates, the father of modern medicine, taught his students here. As you wander among the centuries-old columns, temples, and terraces, you’ll get a real sense of how magnificent this sanctuary once was.

What impressed me most were the breathtaking views. From the upper terraces, you’ll enjoy panoramic views over Kos Town, the surrounding countryside, and the turquoise waters of the Aegean Sea. For me, that alone made the visit worthwhile. Allow around one and a half to two hours to explore the site at a relaxed pace.

If you’d like to learn more about the fascinating history of this remarkable site, consider booking an entrance ticket with an audio guide in advance. It provides plenty of additional background information and helps you get even more out of your visit to one of Kos’ most impressive archaeological landmarks.

10 – Relax in the natural hot springs at Therma Beach

One of the most unique places to visit on Kos is undoubtedly Therma Beach. Located on the island’s east coast, about 12 kilometres from Kos Town, this beautiful spot is well worth the trip. We cycled there by e-bike, and the route itself was part of the experience, offering stunning coastal views along the way.

Once you arrive, you’ll park at the top of the cliffs before walking about ten minutes down a fairly steep path to the beach. Sturdy shoes are definitely recommended. At the bottom, you’ll be rewarded with a unique pebble beach where naturally heated spring water flows directly into the sea, creating warm natural pools that are perfect for relaxing.

After your walk, you can enjoy a drink at the cosy beach bar by the shore. There’s also a café near the parking area with beautiful views over the coastline. For me, Therma Beach was one of the most memorable places on Kos. The combination of the scenic hike, the warm thermal water, and the spectacular surroundings makes this an experience you shouldn’t miss.

11 – Visit the mountain village of Zia and watch the sunset

Ask anyone which place you absolutely shouldn’t miss on Kos, and chances are they’ll say Zia. This charming mountain village is famous for its spectacular sunsets and is one of the island’s most popular attractions. Keep in mind that it gets very busy around sunset, especially during the summer months.

We arrived around 5:00 PM, which I found to be the perfect time. The village was still relatively quiet, giving us plenty of time to wander through the narrow streets, browse the local shops, and enjoy a drink on one of the terraces before the crowds arrived later in the evening.

Don’t limit your visit to the village’s charming shopping street. Continue walking to the small white church above the village, where you’ll be rewarded with stunning views over Kos and the surrounding mountains. This is also the starting point of the well-known hike to Mount Dikeos, the island’s highest peak at 846 metres. If you enjoy hiking, the challenging climb is rewarded with breathtaking panoramic views over Kos, the neighbouring islands, and the Turkish coastline.

If you don’t want to rent a car, scooter, or e-bike yourself, you can also join an organised excursion to Zia. It’s an easy way to enjoy the village and its famous sunset without having to worry about parking or driving back after dark.

12 – Explore the abandoned village of Paleo Pyli

Want to step back in time? Then a visit to Paleo Pyli is a must. This abandoned mountain village was once the medieval capital of Kos and was built on a strategic hilltop to protect its inhabitants from pirate attacks. Today, you can wander among the ruins of old houses, Byzantine churches, and the remains of an impressive castle. It truly feels as if time has stood still.

If you want to enjoy the best views, you’ll have to earn them. The climb to the castle is steep and rocky, so sturdy walking shoes and plenty of water are essential, especially during the warmer months. But trust me—the effort is absolutely worth it. At the top, you’ll be rewarded with breathtaking panoramic views over Kos, the sea, and the surrounding mountains.

After your hike, treat yourself to a drink or a traditional Greek lunch at the taverna opposite the entrance to Paleo Pyli. It’s the perfect place to relax while enjoying the beautiful scenery.

13 – Spot flamingos at Tigaki Salt Lake

Looking for something a little different? Then be sure to visit Tigaki Salt Lake. Located near the popular beach resort of Tigaki, this vast salt lake is a paradise for nature lovers and photographers.

Depending on the season, you can spot a variety of bird species here. The biggest attraction is undoubtedly the flamingos, which usually visit during spring and autumn. Even if there aren’t any flamingos around, the salt lake is still a beautiful place for a short walk. The white salt flats, shallow water, and surrounding mountains create a unique landscape.

We combined our visit with a stop in Tigaki, which I can definitely recommend. First, enjoy the peaceful surroundings of the salt lake before heading to the beach for lunch or a drink. If you’re into photography, try to visit early in the morning or during golden hour, when the soft light makes this landscape even more photogenic.

14 – Explore Antimachia Castle

Antimachia Castle is one of the most impressive historical sites on Kos. Built in the 14th century by the Knights of Saint John, this large medieval fortress was designed to defend the island against enemy attacks. Today, visitors are free to explore the ancient walls, ruins, and charming little churches that still stand within the fortress.

What impressed me most were the incredible views. From the castle walls, you’ll enjoy panoramic vistas over the island’s countryside, coastline, and the turquoise waters of the Aegean Sea. On a clear day, you can even spot several neighbouring islands.

Best of all, admission is free, and it’s usually much quieter than many of the island’s other attractions. Take your time to wander through the fortress, discover its hidden corners, and enjoy the spectacular scenery. Don’t forget your camera—this is easily one of the best viewpoints on Kos.

15 – Visit the traditional windmill of Antimachia

Curious about what life on Kos was like in the past? Then make sure to visit the Traditional Windmill of Antimachia. This beautifully restored windmill is fully operational and still grinds grain into flour using traditional methods.

During your visit, you’ll join a short guided tour of around fifteen minutes. You’ll learn how the windmill works and watch grain being milled into flour. It’s a fun and interactive experience that offers a fascinating glimpse into the island’s traditional way of life.

At the end of the tour, you’ll even receive a tasty souvenir: a few biscuits baked with flour produced by the windmill itself. It’s a lovely keepsake and a delicious way to experience local traditions.

Although there is an entrance fee, I thought it was well worth it. If you’re looking for something different from beaches and archaeological sites, this is a wonderful stop during your road trip around Kos.

16 – Meet peacocks, ducks, and cats at Plaka Forest

Need a break from the heat? Then Plaka Forest is the perfect stop during your road trip around Kos. This shady pine forest is home to free-roaming peacocks and ducks that often wander right up to visitors, making it a fun place for both families and animal lovers.

During our visit, we met a lovely British couple who have been caring for Kos’ stray cats for years. They founded Kitties of Kefalos, a charity that provides food and medical care for many of the island’s cats. Between 10:00 AM and 1:00 PM, they also sell bags of food that visitors can use to feed the ducks and peacocks in the forest. All proceeds go directly towards supporting the cats.

One important tip: outside these hours, you may encounter a man who claims to be responsible for caring for the animals in Plaka Forest and asks visitors for money. According to the volunteers from Kitties of Kefalos, this is a well-known scam. If you’d like to support the animals or the cat charity, only purchase food from Kitties of Kefalos during their official opening hours.

Personally, I found Plaka Forest to be one of the island’s most unexpected highlights. Walking among free-roaming animals in the cool shade offers a completely different experience from Kos’ beaches and historical sites.

17 – Relax on the beaches of Kefalos

For me, the beaches around Kefalos are among the most beautiful on Kos. Here you’ll find a long bay with crystal-clear turquoise water, golden sandy beaches, and a much more relaxed atmosphere than around Kos Town. Despite the stunning scenery, the area feels far less touristy, making it the perfect place to unwind.

The best-known beach is Agios Stefanos Beach, where you’ll enjoy beautiful views of the iconic islet of Kastri with its charming white-and-blue chapel. Feeling adventurous? Rent a kayak or pedal boat and paddle across to the island yourself.

Be sure to continue to Kefalos Beach as well. This wide sandy bay is perfect for spending a relaxing afternoon. The shallow, crystal-clear water is ideal for swimming, while the beachfront is lined with cosy beach bars and traditional tavernas where you can enjoy lunch or a cocktail with a sea view.

For me, this was one of the most beautiful places on the entire island. The combination of the turquoise sea, peaceful atmosphere, and views of Kastri makes Kefalos an absolute must-visit.

18 – Visit Agios Ioannis Thymianos Monastery

Hidden among the hills near Kefalos lies one of the most peaceful places on Kos: Agios Ioannis Thymianos Monastery. Even the drive there is worth the trip, taking you through rugged landscapes with stunning coastal views along the way.

The small whitewashed monastery has a wonderfully tranquil atmosphere. Take a walk around the grounds, step inside the little church, and simply enjoy the silence. Unlike many of Kos’ more famous attractions, you’ll often have this place almost entirely to yourself.

Monastery of Agios Ioannis Thymianos, Kos, Greece

What makes this monastery truly special is its location. From here, you’ll enjoy breathtaking views over Kefalos Bay, the surrounding hills, and the sparkling Aegean Sea. It’s the perfect place to slow down and appreciate the beauty of the island.

If you’re already exploring the Kefalos area, I highly recommend combining your visit with Agios Stefanos Beach or Kefalos Beach. That way, you’ll experience not only some of Kos’ most beautiful beaches but also one of its most peaceful hidden gems.

Bezienswaardigheden buiten Kos

19 – Take a day trip to the volcano of Nisyros

Looking for something completely different during your holiday on Kos? Then a day trip to the volcanic island of Nisyros is an absolute must. From the harbour of Kardamena, it’s about a one-hour ferry ride to this fascinating island. Upon arrival, a bus takes you to the island’s famous volcanic crater, while your guide shares interesting facts about the history of both Nisyros and its volcano.

The highlight of the excursion is undoubtedly walking inside the volcanic crater. You’ll descend to the crater floor, where you’ll see bubbling mud pools, rising steam, and a dramatic volcanic landscape. At times, it almost feels as though you’ve landed on the moon.

After visiting the volcano, you’ll explore Mandraki, the charming capital of Nisyros. Wander through its narrow streets lined with whitewashed houses and blue accents, visit the beautiful Panagia Spiliani Monastery, and enjoy some free time to explore at your own pace. Stop for a traditional Greek lunch, relax at a café, or browse the local shops for souvenirs before boarding the ferry back to Kos.

If you’re looking for a day trip that combines spectacular scenery, fascinating history, and authentic Greek charm, a visit to Nisyros is without a doubt one of the best excursions you can take from Kos.

20 – Discover three Greek Islands on a boat trip

Want to explore more than just Kos? Then a Three Islands Cruise is one of the island’s most popular day trips. During this boat excursion, you’ll visit the islands of Kalymnos, Plati, and Pserimos. Along the way, you’ll enjoy stunning coastal views, several swimming stops, and a delicious Greek lunch served on board.

Your first stop is Vathi, a picturesque village on Kalymnos. Nestled along a narrow natural bay that is often compared to a fjord, it’s one of the island’s most beautiful spots. You’ll have around an hour to wander through the peaceful streets, take photos, and sample some local delicacies.

Monastery of Agios Savvas, Pothia, capital of Kalymnos, Dodecanese, Greece

After exploring Kalymnos, you’ll enjoy a traditional Greek lunch on board, including souvlaki, salad, tzatziki, and fresh bread. A vegetarian option is also available. The boat then passes several fish farms, where you might even be lucky enough to spot wild dolphins.

Next, it’s time for a refreshing swim stop at the tiny island of Plati. The crystal-clear turquoise water is perfect for swimming, snorkelling, or simply relaxing on deck. The final stop is Pserimos, a peaceful little island where you’ll have about an hour of free time to stroll around, enjoy a drink at a waterfront café, or take one last swim before heading back to Kos.

If you’d like to discover several Greek islands in a single day while enjoying sunshine, crystal-clear waters, and a laid-back holiday atmosphere, this boat trip is one of the best excursions you can take from Kos.

21 – Take a day trip to Bodrum in Turkey

Did you know that you can be in Turkey in less than an hour from Kos? Ferries depart daily from the harbour of Kos to Bodrum, making it incredibly easy to visit another country during your holiday. After passing through passport control, you’ll have the rest of the day to explore this vibrant coastal city at your own pace.

Bodrum is a lively seaside destination known for its charming harbour, narrow streets, whitewashed houses, and relaxed Mediterranean atmosphere. Be sure to visit the impressive Bodrum Castle, stroll along the marina, or explore the remains of ancient Halicarnassus, once home to one of the Seven Wonders of the Ancient World.

If you’d like to experience Turkish culture, wander through the colourful bazaar, where you’ll find everything from spices and ceramics to carpets, clothing, and unique souvenirs. Don’t miss the chance to enjoy an authentic Turkish coffee or tea, and be sure to try local favourites such as kebabs, mezes, or a traditional Turkish dessert.

Looking for even more relaxation? Consider visiting a traditional Turkish bath, or hammam, for a truly authentic experience.

I visited Bodrum a few years ago and was pleasantly surprised by how much I enjoyed it. The lively atmosphere, beautiful harbour, and combination of history, great food, and shopping make it one of the best day trips you can take from Kos. It’s a wonderful way to add a second country to your holiday without much extra travel.

Kos truly exceeded my expectations. Of course, the island is famous for its sunshine, beautiful beaches, and delicious Greek cuisine, but it has so much more to offer. From ancient ruins and charming mountain villages to hidden coves, breathtaking viewpoints, and unforgettable day trips to nearby islands, or even Turkey, there’s something here for every type of traveller. Thanks to its compact size, it’s easy to explore a surprising amount of the island in just one holiday. I hope this guide to the 21 best things to do in Kos helps you plan your perfect trip. Whether you’re passionate about history, nature, beaches, or great food, Kos has something for everyone. Most importantly, don’t be afraid to wander off the beaten path every now and then. That’s often when you’ll discover the island’s most beautiful hidden gems.
