Kos Town: Glass-Bottom Boat Cruise with Swimming Stops

A glass-bottom boat ride is fun until you actually see what is under you. This Kos Town trip mixes easy sea views, a pass at an old shipwreck, and a proper swim stop near Pserimos that is the main reason people rave about it.

I like that the experience is short but not rushed, about 2.5 hours total. You get time on deck for sun and sea air, then time for the underwater look through the glass-bottom areas.

One thing to consider: the glass-bottom setup depends on the viewing panels, and a reviewer noted the plastic cover can have scratches that make the view less crisp than you might hope.

Key Points That Make This Cruise Worth Your Afternoon

• Pserimos swimming cove with very clear water, plus time to relax in the sun
• Old shipwreck you can spot from above, with the best views coming at the right moment
• Two glass-bottom viewing areas, so you are not stuck fighting for a single window
• Family-friendly water time, including a slide and support gear for less confident swimmers
• A guide who explains what you are seeing, including historical context, not just commentary for show
• Onboard comfort beats you-guess-the-weather tours, with shaded seating and an upstairs deck

Getting on the Yellow Dorry in Kos Town

You start in Kos Town, right by the port, where you look for the Yellow Dorry Glass Bottom Speedboat. The whole thing is built for an afternoon rhythm, not an all-day shuffle.

Once you are aboard, the boat design gives you options right away. There is a top deck for sun and photos, plus shaded seating if the Greek midday heat shows up early.

The Ride Setup: Deck Time, Shade, and a Bar You Will Use

This is a speedboat, so expect motion. When conditions are a bit choppy, I like that you have a clear choice: sit where you feel best, then switch if needed.

If you want a drink, there is a bar onboard, but drinks are not included in the price. Reviews mention the bar offerings include soft drinks and beer, and snacks are available to buy if you get peckish.

A small practical note: seating can fill up. One reviewer said they boarded early and still found the boat crowded, which is why you should show up with a little buffer rather than banking on empty space.

How the Glass-Bottom Viewing Really Works

The core hook here is the glass-bottom viewing. You have two glass-bottom viewing areas, which matters because it spreads people out a bit and reduces the “one window, ten elbows” problem.

You are also not just looking at random blue water. The trip includes a pass by an old shipwreck, so the underwater viewing has something specific to focus on.

Still, keep expectations realistic. One review pointed out the viewing experience can feel a bit underwhelming if the cover over the glass is scratched or cloudy, even if the glass-bottom concept sounds perfect on paper.

The Shipwreck Moment: Brief, But Memorable

The old shipwreck is one of the two headline sights, and it is timed into the cruise so you see it from above while you are still in “sightseeing mode.” When the boat turns and you are in the right position, the shipwreck becomes the moment that everyone slows down for.

Guides also add context during the ride. One reviewer mentioned learning more about island history and even the role of the place for medicine, which gives the wreck stop more meaning than a quick glance.

If you want better viewing, do what feels obvious but people skip: move closer when the wreck is at its clearest angle. On a moving boat, the difference between correct position and half-aimed looking can be huge.

The Pserimos Swim Stop: Why This Is the Main Event

The swimming stop is the real payoff. The water near Pserimos is described as crystal clear and even green-blue in places, and that matches what makes people come back for a second trip.

This is not a “splash and go” stop. You get a window to swim, float, and enjoy the beach area, which is why the water-time feels like a mini beach day rather than a rushed break between sights.

Snorkeling-style fun is easy, even if you do not plan a full gear setup. One reviewer said to take a snorkel, and another noted goggles and pool noodles are available, so you can jump in and figure it out on the spot.

Water Confidence Support: Life Vests, Floating Devices, and a Slide

This cruise is built to work for different comfort levels. Reviews mention floating devices onboard, and at least one mention says there are life vests for non swimmers, which helps kids and adults relax more quickly.

Kids also get their own entertainment. Several reviews mention a slide into the sea, plus the simple pleasure of jumping off the boat side when conditions allow.

If you or your group is unsure about swimming, pick the spot where you can keep your feet or hold on. The boat gives support items, but it still helps to treat it like a calm swim first, then add the more adventurous stuff.

Onboard Comfort When the Sea Feels Spicy

A glass-bottom boat cruise is fun, but you are still on open water. If you are prone to motion sickness, the best strategy is to choose seating that feels stable and to stay near the center of your comfort zone, then adjust.

One review described a moment where a child felt unwell, and the crew helped by suggesting an upstairs deck seat. That is useful practical advice for you too, if you notice anyone getting queasy.

Also plan for sun. There is shade onboard, but you will likely spend time upstairs at least at the start or between stops. Bring sunscreen, and consider something light for your shoulders, especially if you bruise easy from sun.

What You Actually Get for $23 Per Person

At $23, this cruise is strong value because you get two different experiences in one: underwater sightseeing and real water time. Many Kos tours either focus on the views only or focus on the swim only, and this one gives you both.

It also avoids the full-day trap. Reviews highlight that people chose this because they did not want to commit a whole day, and the duration of about 2.5 hours fits an afternoon slot perfectly.

Where the value shows up most is your decision power. If your group includes non swimmers, they can enjoy the shipwreck viewing from the glass-bottom areas and still feel like they did something “real,” not just sat on a boat.

Best Timing and How to Avoid a Crowded Boarding Moment

A common theme in reviews is crowding around boarding and seating. If you want the best chance at an outside top-deck seat, get there earlier rather than right on time.

If you prefer a calmer experience, aim for the sailing that matches your energy level. Short rides are great when you want something cheerful but controlled, not a marathon.

Also note that you will be on a schedule. You do not control when the shipwreck is shown or when the swim stop happens, so treat the time like a set experience rather than something you can linger and stretch at will.

Who This Cruise Is Perfect For

This is one of those trips that works across age groups. Reviews repeatedly call it family-friendly, and the mix of glass-bottom viewing, shipwreck interest, and swim time is a rare “everyone gets something” combination.

It also fits couples and friends who want a low-stress day. You are not dealing with long transport, and the experience is short enough that you can still do dinner afterward in Kos Town.

If you are traveling with kids, this is especially handy because there is enough to keep them engaged. The shipwreck viewing gives them a goal, then the swimming stop turns the whole thing into playtime.

Who Might Want to Rethink It

If you are chasing a high-end underwater viewing experience only, you might find the glass-bottom part less impressive than expected, especially if the viewing panels are scratched. The water swim is the main star, so plan your expectations around that.

If you are extremely sensitive to boat motion, choose your seat carefully. The cruise lasts about 150 minutes, so it is not a long exposure, but it can still be uncomfortable if you are unlucky with waves.

Should You Book This Kos Town Glass-Bottom Cruise?

I think you should book it if you want a straightforward afternoon in Kos Town that combines shipwreck spotting with a real swim near Pserimos. At $23, the value comes from doing both sightseeing and water time without eating up your entire day.

Skip it only if you mainly want flawless underwater optics from the glass-bottom areas. In that case, focus your expectations on the swim stop, and know that the shipwreck viewing is part of the experience, not the only reason to go.

If your group includes kids, cautious swimmers, or people who just want sun and fun, this is the kind of trip that makes everyone leave smiling.
