You’ll sail Santorini’s caldera by catamaran with a local crew—swimming at Red Beach and Thirasia island, soaking in volcano hot springs, and sharing fresh BBQ onboard as Oia’s cliffs drift past. Expect easy laughter with fellow travelers and moments of real quiet as sunset colors spill across the Aegean.
The first thing I noticed was the color—the sea around Ammoudi Bay is this impossible blue that looks fake until you’re right there, feet dangling over the side of the catamaran. We set off from under Oia’s cliffs, and I kept glancing back at those white houses stacked like sugar cubes. Our skipper, Yannis, waved us to the front for photos (“the light’s better here!”), and I tried to balance my wine glass without spilling it. There was a salty smell mixed with something floral—maybe thyme from the hills?—and a bit of engine oil, not unpleasant. I didn’t expect to laugh so much with strangers but somehow we all did.
We stopped near Thirasia island for swimming. The water was cold at first but clear enough to see little silver fish darting around my toes. Someone handed me a snorkel mask and I gave it a go—awkwardly at first (pretty sure I looked ridiculous). Lunch was already grilling when we climbed back on board: smoky seafood, Greek salad, bread still warm from the sun. The crew kept offering more wine and even vegan options for one couple. I liked that nobody rushed us; we just drifted along, talking or not talking.
Later we sailed close to the volcanic cliffs—the rocks look burnt and ancient—and then stopped by the hot springs. The water turned rusty orange near the volcano, warmer than I expected. My skin felt odd after, kind of tingly. Passing White Beach and then Red Beach, everyone went quiet for a minute just watching how the colors changed as the sun started dropping lower. And then someone said something about never wanting to leave this boat—which honestly, yeah.
