Marina Gialos Beach

Platis Gialos is Sifnos' most developed beach, and the marina here puts you right in the middle of it — a lively strip of cafes, restaurants, and seaside villas backed by one of the island's largest sandy bays. Yacht services are available on the left side of the bay, though holding can be patchy so it's worth taking your time to find a solid spot. When you're done, everything you need is within easy walking distance along the waterfront.
