Sail the Santorini caldera on a private, all-inclusive catamaran cruise from Vlychada. Swim at volcanic hot springs, explore boat-only beaches like White Beach, and time your return for a spectacular caldera sunset.
More ways to explore the area's outdoor wonders
You step from the dock at Vlychada and the catamaran rocks gently underfoot, the Aegean wind already testing the sail. The caldera walls rise dark and raw to star the horizon; below, the sea flashes every shade of blue as the boat threads between volcanic islets. Onboard, the crew opens a cold bottle and the island’s geology and sea spray become the day’s steady companions.
