Step aboard the famous Poseidon Submarine and discover Rhodes from a completely different perspective — above and below the sea.

Departing from Mandraki Harbour, in the heart of Rhodes Town, this unique experience combines sightseeing, underwater exploration, and family entertainment in one unforgettable cruise.

As the boat sails along the beautiful coastline of Rhodes, enjoy panoramic views of:

Mandraki Harbour
the Medieval Old Town walls
Elli Beach
the Aquarium of Rhodes
the area where the legendary Colossus of Rhodes once stood

Then the real magic begins.

Head down into the air-conditioned underwater observatory, located below sea level, and enjoy spectacular 360° underwater views through large panoramic windows.

Watch schools of colourful Mediterranean fish swimming right beside your seat while exploring the marine life of the Aegean Sea in comfort.

One of the highlights of the experience is the live diver show, where a professional diver enters the water and feeds the fish directly in front of your window — creating an unforgettable moment for both children and adults.

Unlike a real submarine, the Poseidon remains safely above sea level at all times, making this experience ideal for families, children, couples, and visitors of all ages.

Whether you are looking for a relaxing sightseeing cruise, a unique family activity, or the perfect way to see Rhodes from the sea, the Poseidon Submarine is one of the island’s must-do experiences.
