Spend five hours cruising Santorini’s caldera on a semi-private catamaran with stops at Red Beach, Mesa Pigadia (Black Beach) for a BBQ, and the thermal springs of Nea Kameni. Small-group pace, snorkeling and an open bar make this a relaxed sea-day that doubles as a geological tour.

The catamaran slips away from the quay and the caldera opens: cliffs rise like folded pages and the Aegean pushes you gently forward. Sea spray cools the deck as the captain eases toward Red Beach — a scar of iron-rich cliffs you can only reach by foot or admire from the water — then along the ivory lip of White Beach that exists only for boats.

The catamaran slips away from the quay and the caldera opens: cliffs rise like folded pages and the Aegean pushes you gently forward. Sea spray cools the deck as the captain eases toward Red Beach — a scar of iron-rich cliffs you can only reach by foot or admire from the water — then along the ivory lip of White Beach that exists only for boats.
This five-hour semi-private cruise (small-group style) stitches together Santorini’s recent geological drama and living coastal culture. The island’s dramatic caldera formed in a massive volcanic eruption; Nea Kameni’s black lava flows and hot springs are reminders that the rocks here are still working. Locals have long fished and grilled in these coves, and the on-board BBQ continues that practical, sea-born tradition.
Expect three main stops: observation at Red Beach, a swim and BBQ by Mesa Pigadia (Black Beach), and a thermal soak near Nea Kameni’s warm waters, plus close passages by the caldera rim and the old lighthouse. Snorkel gear is available; an open bar and bottled water are provided. The pace mixes relaxed cruising with short active swims and boarding from the water.
Practical notes: the trip runs ~5 hours, suitable for most fitness levels but not recommended for pregnant travelers or those with serious heart conditions. Bring reef shoes, sun protection, and seasickness medicine if you’re prone to it. Arrive with a lightweight day pack, towel, and your travel documents if joining from a cruise ship. On calm afternoons the light is excellent for photos; on windy days expect more motion and a bracing ride.
