Excursions -The best golden beaches are in the southwest part of Naxos Island. The south west coast is almost one long sandy beach. The northern part of the island is green verdant and mountainous. The central part of the island -around Chalki village- is planted with olive groves.
In Naxos Town the "Portara" ruins of an ancient temple, the ancient Kouros statues in Melanes and Apollon (the largest in Greece - 7 century BC), the Venetian castle in Naxos Town, small white chapels and churches, monasteries, are all an experience not to be missed.
There are about 500 churches and plenty of Medieval and Venetian castles to visit.

At Danakos is the 12th century Monastery of Photodotis Christ, which it was built by Empress Irene. In Moni, the church of Panagia (Our Lady) Drosiani with beautifull fresco of Panagia Nikopios. The island's port and capital, is a typical Cycladic town with a maze of narrow streets and tiny passages. Hora is a lively town and makes a very good resort. Behind the waterfront an extensive, almost Medieval Old Quarter stretches up the hillside where Kastro (Castle) is. Walking around Kastro is a must while the views will take your breath. The old town up on the hill is divided into two neighbourhoods, Bourgos where the Greeks lived and Kastro (Castle), residence of the Venetian-Catholic nobility.
