A boat on the Santorini caldera gives you a 360-degree sunset experience. To the west, the sun sinks into the Aegean Sea, silhouetting the other islands in the archipelago.Many of the cruises offer dinner and drinks which, with the gentle rocking of the boat, creates quite a romantic atmosphere. Departing in the early afternoon, well before dusk, you also get to check out some of the more remote sightseeing attractions in the area, like the hot springs and Red Beach.
