4/5
280 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.

    Please be aware to get on and off the boat you need to be moderately mobile and there is a rocky walk up a steepish costal hill to a church, so wear good shoes

    Didn't realise it would be finding Nemo themed. I didn't really see the need of the glass bottom, as we didn't really get to see much through it. But overall was a great trip and experience and we enjoyed having the chance to snorkel off the boat.

    The TUI rep Aldo swapped our big boat trip for this. Not happy about it. Although the guide on the ship was brilliant. Pretty pointless to have a glass bottom boat when hardly anything to see. We were out at sea for 2 hours a quick maybe 20 mins swim at paradise beach then another maybe 15 mins at camel bay we were back at our hotel within 4 hours and that Inc a 30-45 min coach ride each way.
