You step down narrow stone steps to Ammoudi Bay or meet the minivan in Vlychada, then the catamaran’s broad hull takes the roll of the Aegean and pushes you away from the whitewashed rim of Santorini. The caldera cliffs recede into a ribbon of blue; wind fills the sails, spray cools your sun-warmed neck, and the smell of charcoal and oregano drifts from the aft where the crew prepares a BBQ.

You step down narrow stone steps to Ammoudi Bay or meet the minivan in Vlychada, then the catamaran’s broad hull takes the roll of the Aegean and pushes you away from the whitewashed rim of Santorini. The caldera cliffs recede into a ribbon of blue; wind fills the sails, spray cools your sun-warmed neck, and the smell of charcoal and oregano drifts from the aft where the crew prepares a BBQ.
Santorini is a scar on the sea as much as a scenic postcard. The island’s caldera formed in a massive eruption around 1600 BCE that reshaped the coastline and left Nea Kameni, the active volcanic isles, at the center of the Aegean. From the boat you pass the iron-red cliffs of Red Beach, reef-framed White Beach and the Venetian lighthouse at Akrotiri—each a chapter in the island’s geological story.
Onboard culture is direct: Greek salads, grilled shrimp and meat, local white wine and a crew who move with practiced ease between safety briefing and service. Expect two snorkel stops in sheltered coves and one warm-soaked swim at the sulfur hot springs (you must swim roughly 100m from the boat). Snorkel gear and towels are provided; alcohol is included but passengers need to be 18+.
Practical notes: the cruise runs about five hours; bring reef-safe sunscreen, a swimsuit, light wind layer and water shoes. If you’re on a cruise ship allow extra time—tender schedules and the cable car can add 45–90 minutes. For calmer evenings, book the sunset sail; for clearer water, choose a mid-morning departure. Seas can be choppy—pack motion remedies if you’re prone to seasickness.
Yes—snorkeling masks and fins are provided and included in the tour price.
Most tender boats drop at Fira’s old port, where vehicle pickup isn’t possible; you must take the cable car to the meeting point and arrive at least 60 minutes before departure.
The springs are warm but require an approximately 100m open-water swim from the anchored boat; anyone uncomfortable with open-water swimming should remain on board or join the other calmer cove stops.
A BBQ featuring shrimp, chicken and sausages plus Greek salads, desserts and an open bar with wine, beer and two cocktails per person are included.
