Gulf of Kefalos Glass Bottom Boat Tour

4.1/5
8 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.

    Ze zouden de naam moeten veranderen. Je kan niets zien door de ruiten, meneer vertelde dat ze daar te laat achter kwamen want toen hadden ze de boot al. De rit zelf prima & gezellig & mooi. Maar niet waarvoor ik een glassboot boekt. Dus wil je gewoon gezellig varen, zwemmen in de zee dan is het hartstikke leuk. Wil je visjes kijken "met kinderen" boek dan een andere boot via kos stad

    Een heerlijke boottoch heel helder water fijn om in te zwemmen. Kapitein met matroos geweldige mensen met veel humor. Zeker een aanrader om zo de golf van Kefalos te ontdekken.

    Heerlijk ochtendje varen. Leuk om even van boord te gaan en kerkje te bekijken en daarna heerlijk gezwommen. Door het glas niet veel te zien, maar dat was niet erg

    Leuke boottocht met schitterende uitzichten. Bezoek eiland Castri met mooi kapelletje is natuurlijk geweldig. Zwemmen bij Paradise Beach en Camel Bay is heerlijk! De glasbodem stelt helaas niet zoveel voor. Paar vissen, vulkaanbubbels en wat relikwieën uit de oudheid gezien. Al met al wel leuke (halve) dag gehad!

    De 'glazen bodem' viel iets tegen. Zijn 4 glazen raampjes. Verder leuk dat je 2x kan zwemmen. Aardig personeel, is een familiebedrijf.
