Sail the Santorini caldera on a small-group catamaran: swim in volcanic hot springs, snorkel turquoise coves, and finish with a BBQ and local wine. Choose a day cruise for swimming or a sunset departure for unforgettable light over the cliffs.
More ways to explore the area's outdoor wonders
A catamaran slips out from the harbour and the caldera opens like a canyon of blue — cliffs rising, white houses clinging above, the sea pulling you toward the volcanic islands at the center. Onboard, the wind rearranges your hat while the captain plots a course by lava rock and light: Red Beach flashes its rust-red cliff face, White Beach appears as a hidden crescent only a boat can reach, and the steam-scented water around Nea and Palea Kameni dares you to step off the ladder.
