    About this experience

    Submarine Poseidon offers you an opportunity to see the most famous and beautiful places in the City of Rhodes. Everything in Rhodes seems a bit more magical when viewed from a boat. A few of the best-known sightseeing include the place where Colossos of Rhodes was standing, the port Mandraki, the Elli beach, the Tourist Harbor and the walls of the Old Town.  Sitting in air-conditioned comfort cabin below the surface, the huge windows offer you 360° panoramic view of the stunning eco-systems of the Aegean Sea. Be sure to have your cameras ready when our diver enters the water and begins to feed the hundreds of multi-colored fish right in front of your window. Our crew will take care for everything. We guaranty, this cruise will be an unforgettable experience for everyone. Enjoy an exciting cruise for about 45 minutes.

    Hour of Chill

    Best part of an hour on the water away from the hustle and hustle of the city. Saw Sea Turtles and schools of different fish underwater, finished by a display by a diver. Son loved it which is all that matters. Would recommend

    It is a nice experience...

    It is a nice experience especially for the kids. The trip is short but enough to experience the seabed and the fishes. We had the luck to see a sea turtle and that was amazing!

    Poseidon Submarine At Mandraki Harbor: questions travelers ask

    Practical detail on this experience, plus the wider planning questions for Rhodes.

    How much does Poseidon Submarine At Mandraki Harbor cost?

    +

    Prices start at $24 per person. The final price depends on the date, the time slot and the number of travelers, and peak weekends in Rhodes usually price higher than midweek mornings. Live pricing and remaining availability are confirmed on the booking screen before you pay.

    How long does Poseidon Submarine At Mandraki Harbor take?

    +

    Plan for about 0.8 hours from start to finish, not counting travel to the meeting point. Most travelers leave another 30 minutes on either side so the rest of the day in Rhodes is not rushed.

    Is Poseidon Submarine At Mandraki Harbor worth it?

    +

    It holds an Outty Ranking of 65 out of 100, which we label "Solid Choice". That score blends traveler sentiment (4.4/5 across 163 reviews), the depth of that review evidence, recent booking momentum, value for money against comparable last minute in Rhodes, and how flexible the cancellation terms are.

    Can I cancel or reschedule Poseidon Submarine At Mandraki Harbor?

    +

    Yes. Cancel free up to 24 hours before the start time for a full refund. Inside that window the booking is non-refundable, and no-shows are not refunded.

    Is Poseidon Submarine At Mandraki Harbor suitable for kids and families?

    +

    Yes, all ages are welcome. Families should still weigh the 0.8-hour running time, and strollers are easier on the earlier, quieter departures.

    How far in advance should I book Poseidon Submarine At Mandraki Harbor?

    +

    Around 57 people booked this in the last 30 days, so popular slots go early. Two to three weeks ahead is comfortable in shoulder season, while summer weekends and holidays in Rhodes can sell out a month out. Same-day spots do open up when other travelers cancel, so it is worth checking if you are already in town.

    What should I bring or wear?

    +

    Bring photo ID, your booking confirmation on your phone, a refillable water bottle and comfortable shoes. Dress for the weather in Rhodes and add a light layer if any part of the 0.8-hour experience runs outdoors or after sunset.

    Where does Poseidon Submarine At Mandraki Harbor start and how do I get there?

    +

    The exact meeting point and directions are on your voucher once you book, and they sit in central Rhodes within reach of public transport. Arrive 15 minutes early: late arrivals are treated as no-shows by most operators.

    What are the best things to do in Rhodes?

    +

    On Outty we rank every Rhodes experience on the same 0 to 100 scale, and alongside this one the highest scorers right now include Makarounas Fishing Boat Trip with swimming stop and BBQ on board, Rhodes Exclusive Swim Cruise Cocktail Open bar & Gourmet Buffet, Athens cruise: Agistri, Moni/Metopi, Aegina with lunch & drinks. The city page groups everything into most popular, highest reviewed, last minute and family-friendly so you can build a day around what actually delivers.

    When is the best time to visit Rhodes?

    +

    Booking patterns follow the same curve: prices and queues climb in peak weeks, while shoulder season gives you better availability on the top-ranked experiences and more room to change plans.

    How many days do you need in Rhodes?

    +

    Three full days covers the headline sights without sprinting. A workable rhythm is one anchor experience each morning, such as this one, an unhurried afternoon in a single neighborhood, then a food or nightlife booking in the evening. Five days lets you add a day trip outside the city.

    Do I book through Outty or through the operator?

    +

    Outty ranks and explains the experiences, then hands you to Viator to complete the booking with the operator directly. The price is the same as booking on Viator yourself, and Outty earns an affiliate commission on the referral, which is how the rankings stay free to read.
