Sail the volcanic caldera on a 5-hour semi-private catamaran, the single most iconic way to see Santorini, gliding past the multicolored Red and White beaches before anchoring to swim in the warm sulfur hot springs off Palea Kameni. A fresh BBQ lunch with local Assyrtiko wine is served on deck while the whitewashed cliff-top villages tower 300m above you. This is the angle the island is famous for and the experience first-timers most regret skipping.
What to expect
You'll board a semi-private catamaran and sail directly into Santorini's volcanic caldera, gliding past the striking Red and White beaches before anchoring in the warm sulfur hot springs off Palea Kameni for a refreshing swim. As you float in the mineral-rich waters, the whitewashed cliff-top villages loom 300 meters above, framing the iconic postcard view the island is famous for. A fresh BBQ lunch is served on deck with local Assyrtiko wine and drinks, allowing you to experience this dramatic landscape from the water—the angle most first-timers regret missing. The full experience unfolds over 5 hours, combining sailing, swimming, and dining into a seamless rhythm of discovery.
Direct wins big. The cruise line's half-day catamaran runs $148-$297 per person (the premium 'Delightful Half Day Sail' is ~$297) for the same product. Booking Spiridakos direct saves roughly $40-$145 per person, and you get a semi-private boat instead of the ship's larger group.
Good to know
Book directly with Spiridakos Sailing Cruises (family-run since 1986) to secure the EUR 100–140 per-person rate and semi-private boat; the cruise line's equivalent offering costs $148–$297 per person. The 5-hour excursion fits comfortably within a standard 6–8 hour port window, though you'll need transportation from the pier to the boat departure point—confirm logistics with the operator when booking. Bring swimwear, sun protection, and a towel; the hot springs are swimmable year-round. Book ahead directly rather than through the ship to lock in savings of $40–$145 per person and ensure a smaller group experience.
