Merichas is Kythnos’ main port where the ferries from Lavrion or Piraeus arrive. This is the most central settlement of the island with buses, rental cars, taxis, and an organized marina for yachts and sailing boats.

The port of Kythnos is also a great place to make your base and explore the island as it has lovely, clear-water beaches, fish taverns with tables on the sand, and shops for basic supplies. From Merichas you can take the boats that regularly leave for the famous Kolona beach or enjoy a magical sunset in this westward-facing settlement.

2. Stroll around Kythnos Chora

Chora or Messaria is Kythnos’ main town, built on a slope of a hill 8 km from Merichas port, a completely car-free village. Chora is a traditional Cycladic settlement that will charm you with all its typical Greek island characteristics:

Whitewashed houses decorated with colorful flowers in a labyrinth of cobblestone alleyways, with arches, chapels, cafes, bars, and sweet shops.

One of the best things to do in Kythnos Chora is to go to Mrs. Floras’ alleyway with colorfully painted houses mostly with flowers and other fun patterns. Mrs. Flora lives in one of the houses and started painting them in 2015. You will love this place!

Kythnos Archaeological Museum

And If you walk to the northeast of Chora you will be happily surprised to find the old windmills, that have been working until very recently. And if you love museums, you can visit the folklore, the Byzantine and the newly opened archaeological museum.

The exhibits are drawn from the ancient city (Vryokastro) and the early settlement of Maroulas, where excavations have been carried out since the 1990s by Alexandros Mazarakis-Ainian.

3. Enjoy Stunning Kolona Beach

The double beach of Kolona in Kythnos Greece

One of the unforgettable things to do in Kythnos is to swim on the double sandy beach of Kolona. This is actually a 240-meter-long sandy land connecting Kythnos with the islet of Agios Loukas and giving you the experience of letting you swim on both sides (one side is much warmer than the other). And if you get hungry there is a good seafood restaurant at the beach (Kolona Experience Restaurant).

There are two ways to get to Kolona beach: either by water taxi from Merichas port (15mins away) or by car which you may find a little challenging as you have to drive over a dirt road.

 Or you can book this amazing Private Sunset Cruise to Kolona Beach with snacks on board and stops for diving to the beaches!

4. Go to Dryopida & Katafiki Cave

Dryopida is Kythnos’ second-largest traditional settlement built in a valley in the center of the island. That gave the small village an extra protection asset from the constant pirate raids so common in medieval times.

Walking through the picturesque alleys of Dryopida and at its northern edge you will get to the entrance of Katafiki cave. Katafiki is one of the biggest caves in Greece, formed by a stream of water that is believed to have been crossing the cave.

The cave has been used by the locals as a shelter and hideout from the pirates, Franks, Ottomans, and other invaders. As they discovered iron inside the cave it was also the mining area for a long time. Even today you can see traces of iron in the cave’s walls and rails, wagons, and similar equipment.

The cave is open during the summer. The guided tour lasts about 15 minutes and it is pretty impressive and detailed. Free entrance, with the option of donations.

5. Find out about the Thermal Springs

Tip: You shouldn’t stay inside the hot bath for more than 15 minutes.

What all those beaches have in common is that they never get too busy like it happens in Paros or Mykonos.

8. Taste the Local Gastronomy

Like any other Greek island, Kythnos has also some local dishes that you have to discover to get the full Kythnos-experience!

My personal favorites are:

  • sfougata, small fried cheese balls
  • kolopi pie with spinach, herbs and lots of spring onions baked in the oven
  • poulos, a bread roll filled with salted pork
  • capersalad, boiled potato, capers, olive oil, lemon or vinegar. The island also has other traditional products such as honey and various types of cheese.

9. Visit Ancient Kythnos Ruins

If you are like me and you love ruins and monuments then you should visit the archaeological sites of Kythnos. Kythnos has been inhabited since the middle stone ages and excavations have shown that the island was probably the oldest settlement in the Cyclades.

The island flourished in classical times and contributed a trireme (ancient galley) in the naval battle of Salamis. The ancient monuments of Kythnos are not organized or easy to reach but they are really worth the visit!

Ancient Vryokastro

Vryokastro Kythnos

Vryokastro was Kythnos’ ancient capital that was inhabited from the 10th century BC to the 6th or 7th AD for more than 1600 years. The excavations have also revealed the ancient port in Mandraki Bay, as well as 2 large statues of the Roman period of the island.

At the top of the Acropolis, there is an important sanctuary dedicated to Demeter, in use from the 8th century BC to the 1st century AD. There is evidence that connects it with the Demeter sanctuary of Eleusis in Athens. There is no asphalt that reaches the archaeological site, so access up to a point is by vehicle and then on foot via a dirt road for about 20-30 minutes. Free entrance.

The medieval Castle of Oria or Kefalokastro

Castle of Oria in Kythnos Greece
Castle of Oria

The Castle of Oria was built 250 meters above sea level, on a hidden rock offering an almost peripheral view of the neighboring Kea. Kefalokastro was Kythnos’ capital during the Byzantine and Venetian eras of the island. Its final abandonment is dated in the 16th century after its fall and total destruction by the Ottomans.

How to access the Castle of Oria

It is not the easiest site to visit but you will be compensated by the stunning wild landscape and the vistas! It is located 4 km northwest of Loutra with an asphalt road up to the last 700 m.where you have to leave the car and walk.

10. Hike Kythnos Trails

Although Kythnos has only low mountains, it offers wonderful trails passing by archaeological and Byzantine sites, windmills, chapels, and stunning beaches. Profitis Ilias is the highest point of the island at just 336 m, the union of two ridges that offer magnificent vistas of the island. There are 15 trails but not all of them are signposted.

My favorite trail is the one that leads to Kythnos’ ancient capital, Vryokastro which offers a wonderful view of Kolona beach.

Tip: You should hike only in Spring or Fall, summer is too hot to hike in Kythnos.

Where to Eat in Kythnos

One of the things that makes Kythnos unforgettable is the food and the mouth-watering recipes that you will taste in the restaurants on the island. Some of my favorite places to dine are:

Kythnos Chora:

  • To Steki tou Ntentzi is a traditional tavern with white tables and chairs under a beautiful canopy of vines in the heart of Chora. Do not miss to visit the inside of the tavern as it is decorated with items from Kythnos’ past, a really beautiful diner
  • For a delicious traditional local dessert go to Tratamento. Taste their own galaktoboureko made with local milk in a pastry, and handmade cherry syrupy sweet


For fresh fish try Ostria restaurant and the seafront Mirra (open all day from brunch) offers eclectic Italian cuisine and meats


Sofrano, the yacht restaurant, with tables right by the sea offering fine seafood cuisine with Peruvian recipes

How to Get to Kythnos

There is a regular ferry connection between Kythnos and Athens. The ferry trip lasts about 3 hours from Piraeus and 1,5 hours if you leave from Lavrion port.
Kythnos is also connected with some other islands of the Cyclades, like Kea, Serifos, Sifnos and Milos.

There is no airport on the island of Kythnos. I use FerryScanner to book ferries to the Greek Islands at great prices.

Best Time to Visit Kythnos

The island is at its liveliest between May and September and in peak season from July to August, Kythnos will be busy, mostly with Greeks. The sea water is at its warmest (25-28 C) in August and September.

I love exploring the islands in the off-season such as April or October, and that means that there will be hotels, cafes, and taverns working, but it will be quiet with just the permanent residents.

When is Best to Go to Greece

Greece has 4 distinct seasons with considerable temperature differences if you are in Thessaloniki in the north or Crete in the south. The islands never close, they have permanent residents but they are at their liveliest between May and September.

Winter is great in Greece for hiking, ski resorts, and exploring archaeological sites.

What does Kythnos mean?

The first inhabitants of Kythnos were the Dryopes whose mythical king was Kythnos (son of the God Apollo), hence the name of the island.
