Santorini Caldera & Thirassia Full-Day Private Cruise: Swim, Snorkel, Winery & Sunset
A private 10‑hour catamaran that threads Santorini’s dramatic caldera, stops for snorkeling at iconic beaches and hot springs, and crosses to Thirassia for a winery visit and village walk — all capped by sunset at Akrotiri Lighthouse.
The Experience
Before You Go
Bring reef‑safe sunscreen
The caldera’s underwater life is sensitive; use reef‑safe sunblock and reapply after swimming.
Wear water shoes
Beaches and landings can be rocky; shoes with good grip make boarding and Korfos Bay comfortable.
Carry small cash
Some taverns and village vendors on Thirassia accept only cash for quick purchases and tips.
Time for sunset
Plan to be on deck near the Akrotiri Lighthouse at golden hour for the best light and unobstructed views.
Local Knowledge
Hidden Gems
- •Korfos Bay on Thirassia — a sheltered pebble inlet accessed by historic stone steps
- •Quiet vineyard terraces above Manolas where small family wineries offer personal tastings
Wildlife

Conservation Note
The caldera’s marine habitats are fragile — avoid touching volcanic rock or marine life, use reef‑safe products, and carry out all rubbish to protect the Aegean.
Santorini’s caldera formed after the massive Bronze Age eruption that reshaped the island and influenced ancient Mediterranean cultures; Thirassia is a remnant of that pre‑eruption landmass.
