More ways to explore the area's outdoor wonders
You step aboard at Vlychada as the wind angles the sail and the island gathers around you: pumice cliffs, black sand coves and the caldera’s sheer rim rising like a cliff-face theater. The boat slips toward Red Beach first; the rust-streaked rock dares you into clear water and easy snorkeling among submerged volcanic outcrops.
