If you’re visiting Rhodes and looking for a relaxing yet captivating way to see the city’s highlights, the Poseidon Submarine experience might catch your eye. Though we haven’t personally tried it, based on reviews and tour details, it seems to be a solid choice for those wanting a quick, family-friendly adventure that combines land views with underwater surprises.
What makes this tour particularly appealing is the affordable price—just over $17 per person—and the unique opportunity to see Rhodes from both above and below the water. Another plus is the air-conditioned cabin, ensuring comfort even on warmer days, and the short duration—about 45 minutes—making it manageable even if you’re tight on time or traveling with kids.
One potential consideration is the weather dependency—poor weather can cause cancellations, which is something to keep in mind if your trip coincides with rough seas. Also, while it’s great for families, those craving a longer, more in-depth excursion might find this a bit brief. Overall, it’s a tour suited best for first-time visitors, families, or anyone curious about seeing Rhodes from a different angle without a hefty price tag.

What You’ll See from the Surface
The tour begins with a view of Rhodes’ iconic landmarks, such as the remnants where the Colossos of Rhodes once stood. This colossal statue is one of the ancient wonders, and although the actual structure no longer exists, many enjoy hearing about its history while gazing at the site from the water. You’ll also get a good look at Mandraki Harbor, the historic port area, along with Elli Beach, a popular spot for locals and visitors alike.
The walls of the Old Town of Rhodes are another highlight, framing the city with centuries of history.

The tour provides a relaxing way to get a panoramic overview without needing to navigate busy streets or historical sites on foot.
Underwater Views and Marine Life
But the real magic happens below the surface. Sitting in the air-conditioned cabin, you’ll find large panoramic windows that offer a 360-degree view of the marine environment. The diver, as noted by travelers, enters the water to feed the fish, creating a lively spectacle right in front of your window.
Reviews frequently mention the diver’s show—feeding multi-colored fish and sometimes even lobsters—adding an engaging element that kids love. One traveler described it as “nice to watch the diver feed the fishes,” noting the added touch of excitement and interaction. Having a diver on-site makes the experience more than just a glass-bottom boat; it’s an active display of underwater life.
What to Expect During the Trip
The cabin’s comfort is a notable feature, especially on warm days. The tour is designed to be accessible and easy to enjoy, making it perfect for people of all ages. Some reviewers mentioned that the group size is limited to 50, which keeps the experience intimate and manageable.
Seating arrangements can vary, but most seem to find the setup sufficient for viewing and photography. The tour also offers drinks and souvenirs for purchase, so you might want to bring some cash for snacks or a keepsake of your underwater adventure.
The Overall Value
At just over $17, this tour is a notable bargain. You get a quick but immersive experience that covers significant sights in Rhodes, combined with the novelty of being underwater. Travelers have called it “good value for money” and appreciate how it offers a different perspective of the city, especially for those who might be pressed for time but still want to see something memorable.
