Just across the water from Skiathos, Arkos offers an easy escape from the busier beaches of the main island. Its sandy coastline and clear waters make it a beautiful choice for swimming, relaxing and spending a few slow hours by the sea.

Accessible by boat, the island has several beaches and remains largely untouched. Arkos is also known for its underwater scenery, with Visit Thessaly noting it as one of the islets visited for diving around Skiathos.
