With its beaches, its village and its port, Íos Bay is almost a must if you visit the island. If you stay there, do not hesitate to snorkel Gialos beach, in the northern side of the bay. If the seabed, covered with sand and seagrass, is quite ordinary, many fish can be seen in the shallows.

How to get to Gialos Beach snorkeling spot?

Gialos Beach is on the west coast of Íos Island, in the Cyclades. Located in Íos Bay, it is very close to the ferry port and the main village of the island.

The recommended snorkeling area is at the boundary between the northern end of the beach and the beginning of the rocks (see map). On foot, you have to walk 600m from the port and 400m from the southern tip of the beach (where there are several restaurants, including the Tropicana Café) to reach the water entrance point. Access is easy, as is parking, except in July-August.

The snorkeling area extends along the rocks that border the north of the beach (see map above). Confident swimmers can consider snorkeling along the coast and exit the water at Tzamaria Beach (about 650m, take a diving flag with you).

This spot is shallow, with a water depth varying between 1 and 6ft/0.40 and 2m. The seabed is quite monotonous, with a small rocky drop-off and large stretches of sand and Posidonia.
