On this semi-submarine cruise, you'll explore the Kolymbia coast from above and below the waves. The boat stays on the surface, but its underwater cabin sits below sea level, giving you up-close views of marine life and rock formations as you sail past Tsambika Mountain. There's time for swimming and snorkelling at Agios Fanourios and Cape Tsambika, too, and if you're up for it, you can even take a few fun jumps off the boat before heading back to Kolymbia Harbour.

We have been on this trip before and knew what to expect. The staff are friendly, helpful and informative. The lady working on the boat was really lovely with the children and spoke to them about the fish. It's a calm, relaxed trip. The underwater viewing area and length of trip are perfect for children.

We enjoyed the whole experience it’s a fantastic trip for families even with young children

Det er en fin lille tur. God til børn da det ikke er hele dagen.

Lovely friendly locals who made you feel like friends rather than customers

Super fin bådtur, meget børnevenlig og stille og rolig hyggelig tur

Alles in allem ein gelungener Ausflug mit gutem Preis/Leistungsverhältnis. Sehr netten Mitarbeiter. Das Unterwasserfenster ist ein netter Zusatz, kann man aber zuwenig nutzen. ( Nur sehr langsame Fahrt) Dauer ist perfekt mit knapp 3 Stunden.
