Kastraki is a great sandy beach on the southwest coast of Naxos. It is located about 17 km from Naxos town (Hora) near the beach of Mikri Vigla. The Kastraki beach is one of the largest beaches of the island, and its length is about 3 km.

Kastraki is an unorganized beach, but a few small tavernas where you can relax and have a snack, and you can also rent sun loungers and sun umbrellas (though it is worth considering that their number is very limited), you will find here. And in the vicinity of the beach there is also a small selection of housing.

The Kastraki beach is never crowded, so it is ideal for those who want to enjoy the sea and sun away from the hustle and bustle and excessive congestion.
