The experience

The boat leaves Platis Gialos marina and heads southwest through the strait between Kytriani and Sifnos, passing the Panagia Kytriani church sitting on a secluded islet. As you continue south, the Polyaigos lighthouse comes into view, standing 130 meters above the sea. The skipper navigates these waters and points out the landmarks. You watch the coastline shift from inhabited islands to the raw, uninhabited landscape of Polyaigos itself.

The route ends at Kalogeros Bay, where the water turns turquoise and the beach is empty white sand. You get time to swim and snorkel using the equipment provided. A platter of cheese and cold cuts, fresh fruit, beer, soda and bottled water are on board. The skipper stays with the boat while you're in the water, and the return to Platis Gialos takes the same route back, giving you four hours total on the water.

Two boat models are available (Marvel RIB or TopLine RIB), and you pick the passenger count that suits your group at checkout. Both are rigid-hull inflatables built for speed and stability in open water. The skipper speaks English and knows the route. Fuel is included in the price.

Is this one for you?Choose the Marvel RIB if your group is larger or you want a faster, more open-water feel. The TopLine RIB suits smaller groups and offers a tighter, more intimate experience. Both boats follow the same route and include the same stops and food, so the choice is about comfort and group size rather than itinerary.
