Santorini Caldera Catamaran Cruise with Volcano Hot Springs & Snorkeling
Sail Santorini’s caldera in five hours: snorkel in sulfuric hot springs, swim at Red and White Beaches, and return to a BBQ on deck. Perfect for travelers who want a compact, active read of the island by sea.
The Experience
Before You Go
Bring reef-safe sunscreen
Sunscreen chemicals can harm marine life and are often restricted; choose a reef-safe formula to protect reefs and turtles.
Wear water shoes with good grip
Rocky boat-to-beach entries and ladder boarding are common; protective, grippy footwear reduces slips and stubbed toes.
Time your choice for conditions
Morning cruises are usually calmer for snorkeling; sunset sails prioritize views and photo light but may have stronger winds.
Carry ID and passport details
Embarkation requires passport/ID details; bring a copy and confirm pickup time if using the hotel transfer.
