Nisyros is a volcanic island south of Kos that lies about an hour’s boat ride from the port of Kardamena. Just 8 kilometres in diameter, visiting this island is one of the more unusual things to do in Kos because you’ll have the chance to actually walk inside its crater!
The volcano is still active, but it’s closely monitored and groups have been hiking up here safely for years. It’s a good idea to go with a guide of course, just so you can make the most of the experience.
3. Dive into the underwater landscape
In Kos, there’s as much to explore on dry land as there is under water. There’s a whole world to see just off the coast in the Eastern Mediterranean, making scuba diving one of the best things to do here.
Never been diving before? No worries. The spot around Kokina Bay is perfect for beginners – and there are plenty of dive schools and experts who’ll help you make the best of it.
Cycladic culture dates back to 3000BC and is found throughout islands in the Aegean Sea. It’s the lesser-known name of those classic Greek casas you see dotted around, loved for their simplicity and unique charm.
This one is located in Kardamena, Kos, and boasts beautiful sea views over beautiful beaches. The villa sleeps three guests and is fitted with modern amenities to provide a comfortable stay. The town is known for its bustling nightlife, and there are some impressive ancient ruins to explore, including a temple to Apollo.
Outside of Kos town, there are a ton of tiny fishing villages that dot the island. Taking yourself on a village-hopping journey around the island is the best way to experience more of what Kos has to offer.
You’ll get to see the Venetian castle of Antimachia, surrounded by olive groves traditional farm houses. The famous Asklepieion is also on the itinerary, home to the Hippocratic Oath.
6. Stroll along the Agios Theologos Beach at sunset
Visiting Agios Theologos Beach should definitely be on your Greece itinerary. Named after a deserted Church nearby, it’s a popular spot to visit at sunset, especially if you want to spark some romance into your trip.
Try some fresh fish dishes at one of the local tavernas here, watch the sun go down, and enjoy the moment. It’s a great way to spend the evening, and perfect for a date night.

Easily one of the best thing to do in Kos is to spend the day swimming in the crystal clear Aegean, spotting dolphins, and exploring Greek culture. On this boat trip you’ll get to do just that, visiting three islands in one day.
Lunch is provided on the boat, and drinks are available to purchase. All you need to bring is some cash and your beach essentials, and you’ve got yourself an unforgettable experience in Kos.
9. Go to a natural spa beach
Therma Beach is a natural spa that was discovered in 1934 by an Italian archeologist. The Ancient Greeks might have gone here in the past, but all we know is that this natural area of hot springs is an absolute must-do if you’re in Kos.
Ancient or not, soothing your muscles here after a day of pavement pounding, sightseeing or hiking in the heat is pretty hard to top. The water is also said to have healing properties, and there’s only one way to find out.
10. Discover the Castle of Antimachia
Antimachia is a Venetian castle built by the Knights of the Order of St John in the 14th-15th Centuries. Whether or not you go as part of a tour, the Castle of Antimachia is well-worth a visit during your time in Kos.
Sitting proudly on a hill overlooking Antimachia town, the castle is in ruins but remains impressive to this day. Inside, visitors will find abandoned Venetian churches and remains of old settlements.

Aside from warm seas and white sand beaches, Kos has a pretty mountainous landscape. Keen hikers should definitely add Mount Dikaios to their Greece travel itinerary; it’s a rewarding climb with incredible views.
If you’re new to hiking or are put off by the heat (fair enough), there are a number of drivers willing to take you on up. Hop in a jeep and tackle those unpaved roads for a real mountain adventure – and be rewarded with those stunning sea views.
13. Explore the abandoned village of Haihoutes
Visiting Haihoutes is one of the more unusual things to do in Kos, and definitely one of the coolest. All the buildings here are in ruins, as most people had left this village by the 1980s. By 2007, there was just one remaining villager.
Today, a traditional coffee house has been set up to try and revitalise the area. Sip an iced coffee among the ruins and think of what was.

14. Hit up Bar Street in Kos Town
By far one of the coolest things to do in Kos after dark is to hit up Bar Street. This appealingly named area has a lively atmosphere where you can sip a couple drinks and let your hair down.
You’ll find Bar Street has a nice combination of travelers and welcoming Greeks. It’s a loud and vibrant area, and the festivities literally go all night long.

15. Spend the day at the beach
No Kos guide would be complete without a mention of the beach. There are heaps in Kos, but we recommend heading to Tigaki Beach for the day. It’s not far from Kos Town, and spans 10 kilometres of the coast.
It’s a Blue Flag beach with watersports, sunshades, sun loungers and plenty of room. Pack a picnic, lots of sunscreen, and you’ll have a perfect day out.
16. Examine the Casa Romana
The Casa Romana is an archeological site located between Kos Town and the Roman Odeon. Having survived from the 2nd Century AD, the Casa displays the Hellenic and Roman architectural style of the time.
Part of the villa, including statues and artwork, are on display in the Architectural Museum. However, visiting Casa Romana itself is the best way to get an idea of the scale and elegance of these stunning houses.
