Platis Gialos is one of the largest sandy beaches of the island and is the most popular choice of Greek visitors.
The beach of Platy Gialos receives awards every year from the FEE, with the blue flag of the European Union indicating its compliance with 32 strict criteria of the programme (cleanliness, organisation, swimming water quality, safety, life guard facilities, first aid, services, facilities, etc.)
On the left side of the bay there is a fishing boat refuge that also provides services to yachts.
In the middle of the village, next to Alexandros Vernikos Square, there is a small open air theatre.
Also of interest is the church of Agia Sofia on the right hand side of the main road.
Local attractions include the White Tower 1.5 km northeast of the beach, one of the 77 ancient beacon towers (‘fryktories’) of the island and the best preserved.
In Platy Gialos there are rooms to let, hotels, restaurants, grocery stores, a tourist office, cafés, and pottery workshops.
Many hiking trails start from the village, heading towards Fikiada, Vathi, and the other central village settlements.
Opposite the beach of Platy Gialos is the uninhabited islet of Kitriani, with its solitary building, the church of the same name, Panagia Kitriani, the oldest church of Sifnos (10th-11th century).
