Discover the charm of a quick Aegean Sea adventure aboard a glass-bottom speedboat exploring Kos and Pserimos, with swimming, snorkeling, and underwater sights.
This tour promises a fast, fun-filled glimpse into the beauty of the Greek islands, specifically Kos and Pserimos, aboard a sleek glass-bottom speedboat called Dory. With an overall rating of 3.1 out of 5 from seven reviews, it offers a casual, family-friendly way to enjoy the sea and its underwater secrets.
What we really appreciate about this experience is the chance to view submerged scenery and historic shipwrecks without getting fully wet—an ideal perk for those who prefer relaxing on deck rather than swimming laps in the sea. The opportunity to choose between sunbathing on the upper deck or relaxing in the shaded lower deck adds a nice touch of comfort.
However, a key consideration is the shorter duration—just 2.5 hours, which means it’s more of a quick tour rather than an in-depth exploration. If you’re after a laid-back, scenic outing with some underwater viewing, this could be just right. It’s best suited for travelers looking for a light, visually engaging experience rather than a full-day adventure.

This tour is essentially a two-and-a-half-hour jaunt designed for those who want a quick, scenic, and engaging sea experience without the commitment of a full-day cruise. It’s hosted by Pulia Tours, a reputable operator offering multilingual guides in English, German, Italian, and French, making it accessible for international travelers.
The journey begins at Port of Kos, a central location that’s easy to access whether you’re staying nearby or arriving by ferry. The boat, called Dory, is described as a swift glass-bottom vessel, which immediately hints at what makes this experience special—being able to peek into the underwater world while cruising at speed.
1. Exploring Kos and Pserimos – The itinerary takes you on a scenic 80-minute ride from Kos to Pserimos, a small island famous for its tranquil shores. The journey itself is part of the fun, with views of the coast and sea, plus the chance to snap some scenic photos along the way.
2. Crystal-clear waters and underwater views – The main attraction is Dory’s thick glass bottom, which allows you to observe the sea floor, marine life, and even an old shipwreck. One reviewer noted that “you might find some captivating sea life revealing itself,” adding a layer of curiosity and discovery that’s quite engaging, especially for families or first-time visitors.
3. Swimming and snorkeling in Pserimos – Once in Pserimos, the boat anchors for a relaxing swimming stop. You can jump into the clear waters, snorkel, or just float and enjoy the sun. The stop is leisurely, giving ample time to cool off after the boat ride.
4. Sunbathing options – The boat features two decks—the shaded lower deck ideal for those who prefer to stay out of direct sunlight, and the sun-drenched upper deck where you can soak up the Greek rays. This versatility caters to different preferences and comfort levels.
The trip is straightforward but offers enough variety to keep it interesting. The scenic cruise to Pserimos is accompanied by views of the coastline and sea, while the glass bottom provides a window into the underwater world. The old shipwreck visible through the glass is a highlight for those interested in maritime history or just curious about what’s beneath the waves.
The leisurely swimming stop is timed to give you plenty of opportunity to snorkel or simply relax on the boat. While some reviews mention that the experience is “more of a quick peek” than an immersive adventure, they also note that it’s a fun, family-friendly activity.

One traveler mentioned that “it’s perfect if you want a quick, fun way to see underwater scenery without the hassle of snorkeling gear or diving,” which captures the essence well.
Another pointed out that drinks are available for purchase on board, so bringing cash or a card is a good idea if you want a cold beverage while cruising. The duration and group size seem manageable, making it a cozy, intimate experience rather than a crowded spectacle.
The tour’s price covers the boat trip itself, but drinks and snacks are not included—these can be bought on board with additional charges. The overall value hinges on what you’re looking for: a short scenic cruise with underwater views and a swimming break. For those wanting a quick taste of the Aegean’s charm, it offers reasonable value, especially considering the unique glass-bottom feature.

This experience is perfect for families with children, couples seeking a quick escape, or solo travelers wanting a relaxing yet engaging activity. It’s especially appealing if you’re curious about underwater scenery but prefer not to snorkel extensively or undertake a full-day excursion.
If you’re short on time but want a taste of the Greek islands’ beauty and underwater secrets, this tour fits the bill. However, if you’re after a more comprehensive exploration or multiple stops, you might feel the short duration limits the overall value.

The Aegean Sea adventure on the glass-bottom Dory offers a compact yet charming way to experience the stunning waters around Kos and Pserimos. With the chance to see a shipwreck beneath the glass, enjoy scenic island views, and take a refreshing swim, it’s a good choice for those who want a light, leisurely activity that doesn’t eat into your day.

If you’re traveling with family or simply want a charming, easy-going experience, this adventure can add a memorable splash to your Greek island itinerary.
