Probably the most amazing things about Sifnos is that it has 365 churches! So if you are a devout, you can go to church every day and never visit the same church in a year. The most famous and the one that is considered the most worth seeing is the church of the monastery Chrysopigi. Every place has special souvenirs, things that are usually handmade there and will always remind you of there. This on Sifnos is the famous Sifnos pottery. The most famous beach on Sifnos island (also the longest in the Cyclades complex) is called Platis Gialos. In the north-east part of the island you can hike to the remains to an ancient tower, known as "The White Tower", which probably dates back to Roman times.
The site of the tower also gives you the opportunity to see a wonderful uninhabited island - Kipriani, where the only building is a deserted old church. At the north-western part of the island you can find a good camping area with all facilities for a pleasant stay. Don't miss the archaeological museum of Sifnos - it features collections of sculptures as old as 6th c. BC - funerary sculptures, statues, parts of architectural complexes like arcs. The other two types of exhibits are pottery and coins.
The other cultural "must" is the Sifnos Folklore Museum - which is located right next to the war memorial (Iroon) on the main square in the village of Apollonia. There you can see traditional clothing, cauldrons, tools. You will learn a lot about the history and culture of the Greek nation. More and more asphalt roads are appearing on Sifnos, but you'll still be able to do most of your walking on the island's distinctive flagstone and marble paths. You'll probably see village women whitewashing the edges of the paving stones, transforming the monochrome paths into elaborate abstract patterns. Throughout Sifnos island, you'll see dovecotes, windmills, and small white chapels in amazingly remote spots. Sadly, the continuity of these fine paths has been interrupted-even destroyed-in many places by the construction of new roads and houses. Our favorite walk on the island leads from Apollonia to Profitis Elias, passing through a valley of extraordinary beauty to the summit of the island's highest mountain, with a short detour to the church and ruined monastery at Skafis. Pick up a walking map at one of the local travel agencies.
The 12th-century walled monastery of Profitis Elias is a formidable citadel, its interior courtyard lined with the monks' cells. The lovely chapel has a fine marble iconostasis. If you continue straight where the summit path branches right, walk through the next intersection. You'll soon reach the church of Skais, situated within the ruins of an old monastery and overlooking a small valley shaded by olive trees. Look for the remains of paintings on the walls of the ruined monastery, in what must have been a tiny chapel. Allow about 4 hours for the round-trip to Profitis Elias, with an additional half-hour for the detour to Skafis.
