Gulf of Kefalos glass bottom boat tour with optional transfers

3.9/5
342 reviews

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 mesmerising 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.

    The boat was over crowded and we were squeezed in thigh to thigh. Reducing max capacity slightly would make it more comfortable

    Too many people on the boat- you were shoulder to shoulder with strangers on the boat. No safety demonstration, the ramp to get on and off the boat was a manky car tyre. not one fish was seen in this excursion. The 4 hour round trip for a 2 hour excursion was ridiculous.

    Was crammed in a small boat with a little window to see bottom of the sea, he’s had a few swings stops and was good to see bubble beach but defo not worth the money that was paid for a few hours

    It was a lovely trip, sadly I felt sick on the coach due to all the windy bends and again on the boat and was sick on the way back. Encourage others to take anti sickness tablets. The guide was informative and funny.
