Kasos has many beaches but most of them, mainly the south ones, are not accessible by road. It is really worth taking the boat to the small nearby Armathia island, where there are a couple of incredible beaches.

• Avlaki (Southwest Kasos): A very small beach in a narrow beach at the southwest edge of the island. Thanks to its position the sea here is calm, even when it gets windy. A bit down the road, heading southeast, you will find the beaches of Hohlakia and Helatro. The easier way to get to the beach is by sea, but there is a downhill path leading here from the Agios Georgios monastery.
• Helatros (Southwest Kasos): An impressive beach thanks to the huge rocky volumes that surround it. It has pebble, clean blue sea and easy road access through an asphalt road.
• Marmara (Northwest Kasos): An amazing beach of exotic beauty with turquoise sea and white sand, one of the most impressive beaches of the Aegean. You will find it on the nearby Armathia island, a bit northwest of Kasos, with boats leaving from the harbor.
• Karavostasis (Northwest Kasos): A beautiful beach with light sand and turquoise sea which is also located on Armathia island. Behind the rocks there is also the small beach of Ypapanti, which is ideal for seclusion.
• Emporios (North Kasos): An organized stretch of sand with little pebble here and there. It offers clean blue sea, a few umbrellas with sunbeds, taverns and rooms to let. You can easily reach it through the main road.
• Ammoua (North Kasos): A small beach with sand at the north side of the island, a bit west of Fry. Make sure you pack your umbrellas because the beach has no natural shade.
• Antiperatos (North Kasos): In the area of Antiperatos, a bit west of Fry, you will find some small consecutive beaches with thin pebble, dark sand and crystal sea. It rarely gets crowded here and one of the main reasons is the exposure of the beach to the winds. You will have no trouble reaching these beaches.
