Sail Santorini’s southern coast on a semi-private catamaran: snorkel the Red Beach, swim in volcanic hot springs and finish with a BBQ and sunset over the caldera. Limited to 18 guests, this five-hour cruise balances iconic sights with relaxed swimming stops.
More ways to explore the area's outdoor wonders
You step onto a low-slung catamaran at Vlychada as the Aegean slips into late afternoon—salt on your lips, a steady deck beneath your feet, and space enough for 18 guests to spread out without crowding. The boat eases away from the marina and Santorini’s cliffs open like a geological story: black lava faces, banded pumice, and the whitewashed edge of the caldera.

Santorini’s present caldera formed after a massive Bronze Age volcanic eruption; the island’s cliffs expose layers of lava, pumice and tuff tied to that event.
Conservation
