The largest coastal village and port of the island, Kamares, is located in the western part of Sifnos, 5 km from Apollonia, the island’s capital. The area owes its name to the caves that surround it and features a large tourist development with infrastructures covering all budgets and tastes.

Agia Marina is located in "Pera Panta" as the locals call the part opposite the village, which is named after the church on the hill. It is built at the foot of the hill of Agios Simeon, it is a point of reference for its all-white houses, while it also features tourist infrastructures.

The organised beach of Kamares (one the largest beaches of the island) stretches between these two villages, with a sandy area and crystal clear waters, and it is awarded a blue flag.

Note that all roads to the rest of the island start from Kamares, as well as interesting paths for hikers to Mavri Spilia (Black Cave), the old mines and the Sanctuary of the Nymphs.
