Kythnos is one of the closest Cyclades islands to Athens and one of the least touristed. The ferry from Lavrio takes under 2 hours, yet most visitors heading to the Greek islands skip straight past it. That means the beaches here are genuinely quiet, even in August. No beach clubs, no queues for sunbeds, and on half the beaches you will not see another person all morning.
The island has a surprising number of beaches for its size. The coastline is indented with dozens of small bays, and the local count puts the total at over 90. Most are tiny, rocky, and reached by dirt track or footpath. The ones worth visiting are spread between the port of Merichas on the west coast, the thermal springs village of Loutra on the northeast coast, and the pilgrimage village of Kanala on the southeast.
A hire car makes Kythnos much easier to explore. The bus connects Merichas, Dryopida, and Loutra but does not reach most beaches directly. Check the Kythnos bus timetable for routes and the how to get to Kythnos page for ferry connections from Lavrio and Piraeus.
Which Kythnos Beach Suits You
The most famous beach on the island: Kolona Beach is a narrow sand strip connecting the main island to a small peninsula, with water on both sides. Depending on the wind, one side is calm and the other has small waves, so you can choose. It is the most photographed spot on Kythnos and looks spectacular from the hill above. Reached by a short boat ride from Merichas or by a rough dirt road and a walk.
Thermal hot springs and a swim: Loutra Beach sits right in front of the village of Loutra, known for its natural thermal springs. The beach is sandy and the water is warm in places where the hot springs seep through. It is a unique combination you will not find on any other Cyclades island.
A proper sandy beach near the port: Martinakia Beach is the nearest good beach to Merichas, walkable in about 10 minutes south along the coast. Sandy, sheltered, and convenient for a swim on arrival or departure day.
Families with young children: Apokrousi Beach on the west coast south of Merichas has shallow, calm water, fine sand, and just enough taverna service to keep a family comfortable for a full day without needing to carry everything.
A long quiet bay on the southeast: Episkopi Beach near Kanala is one of the longest beaches on Kythnos. Sandy, gently shelving, and usually quiet. The small church at one end and the low hills behind give it a peaceful atmosphere.
Something completely remote: Flabouria Beach on the northeast coast is one of those places that feels like it is at the end of the world. A long sandy bay reached by a rough track. No shade, no facilities, no people. Bring everything and expect to have it to yourself.
Near the prettiest village: Kanala Beach sits below the pilgrimage village of Kanala on the southeast coast. It is a small sandy beach with a church on the headland above it and a taverna for lunch. The setting is lovely, and the village itself is worth a wander.
Planning Your Beach Days on Kythnos
Kythnos rewards people who hire a car and explore. The west coast beaches near Merichas are the easiest to reach, but Kolona, the northeast coast, and the bays around Kanala all need a vehicle or a willingness to walk. Some of the dirt roads are rough, so ask locally about conditions before heading to the more remote spots. The Kythnos taxi page has numbers for local drivers.
The Kythnos map shows all beach locations, and the Kythnos photography guide covers the best angles for Kolona and the coastline. Between beach days, the twin capitals of Dryopida and Chora are both worth a morning of walking through narrow lanes and past old churches. The getting around Kythnos page covers all transport options, and for the full picture see our main Kythnos island guide.
