Operated by Caldera Yachting Santorini · Fira (Santorini), South Aegean
Salt spray and limestone cliffs open the morning on a private speedboat that cuts west from Santorini toward the moon-soft shores of Milos. You’ll feel the boat rise and fall as the Caldera gives way to open Aegean; the first stop, Kleftiko, delivers otherworldly rock formations and caves that seem carved by pirate hands and volcanic mood. Half an hour at Polyaigos follows — an uninhabited island where the sand is sparse and the water is luminous blue, offering quiet coves and snorkelable caves.

Suitable for average fitness; you should be comfortable boarding a small boat and swimming from shore or a ladder.

Most speedboats have a small onboard restroom; longer stops on islands provide beach or taverna facilities during the Pollonia break.
