Submarine tour Rhodes: 360° views from Mandraki Harbor

A diver feeds hundreds of fish right outside your window while you sit in air-conditioned comfort.

Submarine Poseidon is a 45-minute underwater tour of Rhodes departing from Mandraki Harbor, where you watch the Colossos site, Mandraki port, Elli beach, Tourist Harbor and Old Town walls from a submerged cabin with 360° panoramic windows. A live English-speaking guide narrates the route, and you watch a crew member feed schools of fish from inside the vessel. The tour skips the lines at the harbor, and the cabin is wheelchair accessible.

The experience

Forty-five minutes below the surface gives you a view of Rhodes that land tours cannot reach. The submarine's 360° windows frame the Aegean ecosystems around Mandraki: the site where the Colossos of Rhodes once stood, the harbor itself, Elli beach, the Tourist Harbor and the walls of the Old Town all pass by at eye level from inside an air-conditioned cabin. The route is fixed, so you move through the same sequence each time, but the marine life changes with the season and the hour.

The centerpiece is the feeding: when the submarine reaches the deeper zones, a diver enters the water outside and begins to feed the schools of multi-colored fish that gather at the windows. Hundreds of them swarm the glass in front of you, close enough to see the detail. A live guide in English narrates the stops and the marine life as you move through the route. The crew handles the logistics. You board, sit, and watch.

You skip the lines that form at the harbor entrance. The submarine departs on schedule and you move straight to the vessel. Infants can ride in a pram or stroller, and the cabin itself is wheelchair accessible. Service animals are allowed on board. Public transportation stops near the departure point if you need to reach Mandraki from elsewhere in Rhodes.

What exactly do I see from inside the submarine cabin?

The Colossos of Rhodes site, Mandraki port, Elli beach, the Tourist Harbor and the Old Town walls all pass by the 360° windows as the submarine moves through the harbor and into the deeper water. The route is the same each departure, so you see the same landmarks and the same stretch of seafloor, but the fish and other marine life vary by season and time of day.

How long does the submarine tour take?

The cruise lasts about 45 minutes from the moment you board until you return to the dock at Mandraki Harbor.

Do I need to arrange transportation to Mandraki Harbor?

Public transportation options are available near the departure point at Mandraki. If you need a transfer from your hotel or the airport, you can arrange that separately. The submarine tour itself departs from the harbor.

What happens when the diver feeds the fish?

A crew member enters the water outside the submarine and begins to feed schools of fish at the windows. Hundreds of multi-colored fish gather at the glass in front of you, close enough to photograph. This happens during the deeper part of the route and is the main event most passengers come for.
