Gulf of Kefalos Glass Bottom Boat Tour

4.2/5
32 reviews

Get a closer look at the underwater world as you explore the Gulf of Kefalos. Perfect for families, our glass-bottom boat adventure makes a fascinating way to experience this stretch of coast. Our first stop is the pinprick Kastri Island, where you can visit a church, stroll around the island, or even stop for a swim at one of the inviting small beaches. Be sure to take a few snaps, as it's the most photographed spot on Kos.

Next, it's off to Camel Beach, a pretty cove flanked by rocks and lapped by azure waters - the perfect backdrop for a swim. Finally, you'll visit the famous Paradise Beach, where the highlight is witnessing the unique bubble phenomenon, a mesmerizing area where streams of bubbles rise into the water from the sea bed.

Our glass-bottom boat ensures you can admire the underwater wonders of the Aegean as you travel from place to place. Don't forget your camera to capture your unforgettable boat trip around the Gulf of Kefalos.

    There was no point having a glass bottom boat as there was nothing to see the whole trip, most on board also spent the majority of time on the boat and not in the sea is it was too choppy and windy. We feel it was a waste of money and quite frankly boring. Defo would not recommend.

    This trip was fab! Easy transfer to the boat, both staff kept it entertaining with jokes and abba music! There wasn’t very many fish along the journey but one of the stops there was loads & the bubbles were interesting too! The sea was warm and we felt safe the entire time, would highly recommend! The half day trip was good too, just enough time to enjoy the trip, didn’t feel rushed or too slow. There were snacks/drinks available if you wanted to buy them. A good day!

    Great trip, perfect length of time. The crew were brilliant. I just felt that there were a few too many people on the boat
