Nas is a small seaside settlement on the northern side of Ikaria, located at the mouth of the Halaris river. It lies in an area of exceptional natural beauty where the river meets the sea.

The area is known for its striking landscape, with rocks, greenery, and clear waters, and nearby archaeological remains from the ancient sanctuary of Artemis. The combination of nature and history makes it unique.

Nas is a popular but relatively low-key destination, especially for visitors seeking relaxation, swimming in a natural environment, and access to trails and beaches in northern Ikaria.
