The island of Sifnos lies approximately in the middle of the triangle formed by Milos, Serifos and Paros. The north and north-west of the island are occupied by a barren range of hills, the east and south by gentler uplands. The coast is much indented and lined by cliffs for much of its length.
Agriculture (particularly onion-growing) on the island’s fertile soil, the manufacture of pottery of traditional type and weaving bring the inhabitants a modest degree of prosperity.
The principal port on Sifnos is Kamares, which is well sheltered, and where you can rent bikes or scooters to reach Apollonia, the island’s capital. From there roads lead to the popular places along the coasts. These are also beautiful anchorages and should really be visited by boat if possible.

The medieval village of Kastro – with remnants of its ancient walls – but also the bays of Faros, Vathi and Platis Gialos are absolutely worth exploring: translucent turquoise water, combined with good tavernas.

Already well populated in the period of the Cycladic culture (3rd and 2nd century BC), the island grew so wealthy in classical times from the produce of its silver mines that the Siphnians built a treasury in the Sanctuary of Apollo at Delphi. When the flooding of the mines made it impossible to work the silver the island declined into insignificance. Entrances to the silver works can be seen near the sea at Ayios Sostis and Ayios Minas.
