About this tour
When Lily from our BugBitten team booked this full-day catamaran cruise out of Vlychada, we were after an easy way to see Santorini's volcanic caldera without the island-hopping hassle. The boat itself — a wide catamaran with proper sunbeds — carries mixed groups of tourists, mostly couples and families keen to swim, snorkel, and eat seafood while the sun does the heavy lifting. You get picked up from your hotel, sailed out to snorkel-friendly spots (often near Ios), fed a Greek spread at sunset, and delivered back by nightfall. It's nine to ten hours depending on sunset timing, and the vibe is relaxed rather than rushed.

What to expect
You'll be collected early morning and ferried to Vlychada, where you board a roomy catamaran. The first few hours are dedicated to sailing towards Ios or quieter Santorini beaches, with time to swim and snorkel in calm, clear water — gear provided. The crew hands out towels, and there's a sociable vibe as groups find their spots on the sunbeds. Lunch arrives mid-afternoon: grilled meats, spaghetti, Greek salad, dips, and fresh bread, washed down with local wine or beer. After eating, most passengers nap or drift back into the water until the captain angles the boat for the westward sail.
The final stretch is the money shot — you're cruising back as the sun sinks behind the caldera, painting the volcanic ridge in gold and pink. The catamaran's size means you can move around without fighting crowds, though it's busy enough that you won't have the deck to yourself. Expect fairly standard tourist company: families, couples, a few solo travellers. The boat docks back at Vlychada as dusk hits, and you're shuttled back to your hotel by around 8 or 9 p.m.

Good to know
If you're not keen on island-hopping or want a solid meal and swim rolled into one day, this delivers. The boat's catamaran design keeps it steady, so even marginal swimmers can relax without feeling dodgy. Hotel pickup removes one planning headache. The included food is actually decent — not gourmet, but proper grilled fish and meat, not just bread rolls. The snorkelling gear is solid, so you can have a proper nose around if you're bothered.
You're crammed with other tourists, so expect 40+ people on the boat — not intimate. The day is fairly full-on from 8 a.m. onwards, and once you're aboard there's nowhere quiet to escape. If you sunburn easily, the reflected light off the water will catch you. The walk down to Vlychada port can be steep if you're not mobile. Gratuities aren't included, so the crew will expect a tip. Kids under two sit on laps (no cost, but cramped). Peak season (June–August) can feel rammed.
Bring suncream (reapply after snorkelling), a hat, and water shoes for the rocky entries. Towels and snorkel kit are provided. Wine and soft drinks are included; beer and spirits vary. Groups run 40–50 people. Book early July through August if you want that guaranteed sunset slot — timing shifts with dusk.
