It’s a popular choice among visitors, with over 80 reviews giving it a solid 4.5-star rating. While it’s not without its quirks, it’s a straightforward, budget-friendly way to see some of the highlights around Pserimos Island.
What we really like about this tour is the comfort of the vessel—it’s shaded, has onboard restrooms, and the crew handles all the navigation, so you can just sit back and soak in the views.

Enjoy being on the water? Here are other boat experiences we've looked into in Kos
The Itinerary: A Closer Look
The trip begins with a scenic view of Kos Harbour from the water, setting the tone for an enjoyable cruise. The first major stop is at Pserimos, a tiny island with a stunning beach. When you arrive, you’ll have about 40 minutes to relax, take photos, and enjoy a swim. The water here is clear, inviting, and perfect for cooling off. Travelers have enjoyed this stop, with one review noting, “Exciting to swim in the blue waters,” and suggesting bringing snacks and drinks for kids.
The second highlight is the shipwreck near Avlakia Beach. This old cargo vessel has become a local landmark, and many find it fascinating to see such a relic in the sea. You only get about 15 minutes here, but it’s enough to snap some great photos and marvel at this piece of maritime history. Several reviews mention the shipwreck as a “brilliant” and “awesome” sight, adding a memorable element to the trip.
Underwater Views and Photo Opportunities
Thanks to the glass-bottom boat, you’ll get a good look at fish and underwater life without getting your feet wet. While some reviewers note that the windows are relatively small—about 20 cm by 90 cm—and that crowds can limit viewing during busy times, the overall experience is still enjoyable. The boat’s design allows a decent glimpse into the underwater world, especially if you sit near the windows.
Comfort and Convenience on Board
A key feature that sets this tour apart from more basic boat excursions is the comfortable vessel. It’s equipped with a shaded area, protecting you from the sun, and restrooms inside, which is a thoughtful touch, especially for longer or hot days. The trip is easy to book with a mobile ticket, and the activity is suitable for most travelers, including those who may prefer a less active day. The crew handles all navigation, so there’s no need for you to worry about steering or directions.
The Swimming and Beach Stop
The blue lagoon near Pserimos is highlighted as the main swimming spot. It’s described as not too deep and great for a relaxing dip. The reviews mention the blue lagoon as an “awesome” place to enjoy the water, with some noting that it was crowded, which can affect the viewing experience from the boat. Still, the chance to swim in crystal-clear waters with friendly fish makes it a bucket-list moment for many.
The Real Experience: Pros and Cons
Looking at the reviews helps paint a more complete picture. Many travelers loved the scenery and the friendly crew, describing the experience as “great” and “brilliant.” The shipwreck is often highlighted as a unique sight, and the swimming in the blue waters is a highlight for all ages. The price point feels justified for the experience offered—considering the scenic views, the stops, and the comfort.
However, not all reviews are glowing. Some travelers experienced booking issues or missed the boat because it departed earlier than scheduled, which underscores the importance of arriving early and confirming your details. Others found the windows small and the crowds overwhelming, especially during peak times. There was also a mention that the trip was canceled without notification, which can be frustrating, so it’s good to keep a close eye on confirmation details.
This tour offers good value for money, especially if you’re after a relaxed, scenic outing rather than an in-depth underwater exploration. It’s perfect if you want a straightforward way to enjoy the sea, take great photos, and spend some time swimming in beautiful waters.
Who Should Consider This Tour?

If you enjoy gentle boat rides, scenic views, and easy access to swimming spots, this trip suits you well. It’s ideal for those who want a relaxing day on the water without complicated logistics or strenuous activities. Families with children might find it enjoyable as well, especially with the onboard amenities and the shallow swimming areas, but be mindful of timing and crowds. If you’re after a more in-depth underwater experience or want to snorkel extensively, this might not fully satisfy that craving.
Travelers who appreciate good value and straightforward sightseeing will find this tour hits the right balance. Those looking for a quieter, less crowded experience should plan to go early or avoid peak season if possible.
