Pedal boat from Crazyshark in front of Kastri Island, Kefalos Bay, Kos 📍 Kastri Island · Kefalos Bay
Our #1 Attraction

Kastri Island -
the icon everyone comes for.

Right opposite our base rises Kastri: a tiny rocky islet crowned by the picture-perfect blue-domed chapel of Agios Nikolaos. It's the most photographed landmark of Kefalos Bay - and the one thing every visitor wants to see up close.

The easiest way? Rent a pedal boat from us and paddle yourself there in minutes. Or join one of our jet ski safaris or boat tours straight to the island.

Brilliant day out around the coast of Kos

"Sotiris is passionate about the ocean, Greece and Kos. A caring, generous host who kept us entertained with his stories. We visited remote beaches for swim stops and the beautiful, magical Bubble Beach. A fantastic day - I cannot recommend it enough!"

Super fun boat trip

"A 2-hour boat trip along the beautiful coastline of Kos with skipper Sotiris. He could tell us so much about the area. We stopped at 2 beautiful places to swim and snorkel - and my sons (9 and 11) were even allowed at the helm. They loved it!"
