You will swim at the long (more than 3 kilometers) beach in front of the settlement with the fine white sand and the crystal clear turquoise sea. There are nice rocks in parts, which form secluded small coves, where you may enjoy the sea almost alone; a place suitable also for naturists. The beach of Kastraki is successive to that of Mikri Vigla and it is equally affected by the strong winds in summer. You may also swim at the next beach, that of Glyfada.
At a distance of less than 2 kilometers eastern to the settlement you may visit the Venetian castle “Pyrgos Oskelou”. Traces of a Mycenaean acropolis are still visible on a site close to the village.
In case of emergence, the corresponding services of the town of Naxos (15,5 kilometers far away to the North) are available for you.
Access to Kastraki is easy from the town of Naxos by rented or private car and motorbikes.
