The boat slips away from Pera Gialos at 10:30, the marina’s low stone quay shrinking as the island’s white houses watch. Wind combs the surface into a silver path and, before long, the boat drops anchor at Red Rock — a sheer, weathered cliff with a small cave that dares swimmers to explore its shadowed lip.

The boat slips away from Pera Gialos at 10:30, the marina’s low stone quay shrinking as the island’s white houses watch. Wind combs the surface into a silver path and, before long, the boat drops anchor at Red Rock — a sheer, weathered cliff with a small cave that dares swimmers to explore its shadowed lip.
This loop of islets highlights Astypalea’s layered past: a crossroads of Aegean sailors, its coastline shaped by tectonic uplift and marine erosion rather than gentle beaches. Koutsomiti is a scatter of rocks and turquoise shelves where seagrass beds host shy fish; Kounoupa’s famous double beach opens like a pair of palms, backed by scrubby hills and a single snack bar serving simple, local fare.
Expect warm, clear water ideal for snorkeling, frequent seabirds, and a relaxed pace set by the crew. The cruise runs roughly 6½ hours, with swim stops (30–40 minutes) and a longer beach stay at Kounoupa for three hours—enough time for a swim, a walk between the two bays, or a cold drink beneath the supplied umbrellas.
Practical notes: snorkel gear, bottled water, and restrooms are onboard; bring reef-safe sunscreen, a waterproof case, and mild-motion-sickness meds if you’re sensitive. Arrive early at the Pera Gialos quay to confirm boarding, and pack a small dry bag for valuables. This day at sea is straightforward—an accessible taste of Astypalea’s wind-sculpted coast for anyone wanting clear water, short swims, and island-side calm.
