Captain Nemo is not an ordinary glass-bottom boat. It is a unique 15m long vessel with an underwater cabin that features 22 large windows 2,20m below the surface.

The boat departs every hour and the cruise lasts 50 minutes. In the beginning, the passengers sit on the top deck and are able to admire the unique cliffs and bays of Paleokastritsa. During the second half of the cruise, the passengers sit comfortably 5 feet below the surface in the air-conditioned underwater cabin. The large glass windows provide spectacular views of the many different sea creatures and fish that Paleokastritsa is famous for.
