Spend a relaxed half-day catamaran cruise around Santorini’s southern coast — swim at sulphur springs, snorkel near volcanic islets and visit Red Beach by boat. Perfect for swimmers and sightseers who want a compact, maritime view of the caldera.
More ways to explore the area's outdoor wonders
Salt air sharpens sight as the catamaran slips from the harbor and the cliffs of Santorini begin to peel away — white villages perched like human-made cliffs above a bowl-shaped caldera. In a single half-day sail you’ll skim past the black- and red-streaked coastlines, circle the volcanic islets of Nea and Palea Kameni and drop anchor in warm sulphur-scented springs where the sea itself seems to push you forward.
