Gulf of Kefalos Glass Bottom Boat Tour

3.6/5
7 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.

    Allt var bra tycker jag förutom busschauffören till båten , han hade ett väldigt dåligt bemötande.

    Att hela resan döps till glasbotten, då förväntar man sig se mer i havsbotten från gladbotten . Självklart vulkanbublorna var fantastiskt fin.

    Liten båt, såg inte alls ut som på bilden.packat med folk, inget stopp för att få köpa vatten eller fika, tog jättelång tid. Glasbottnen var två små rutor. Stod inget om att det skulle stannas vid en ö och tittas på kyrka. Bussturen fr Atlantica togöver en timme enkel resa. Borde informerats om.

    Hvis man tager oplevelsen for glasbundens skyld, så bliver man slemt skuffet. Men badningen fra båden er fantastisk. På vores tur fik en engelsk pige sin finger i klemme på bådens bagerste udklappelige “trappe” til vandet. Hendes finger blev mast til halv størrelse og neglen lignede en der hurtigt ville falde af. Forstår ikke at båden ikke gik mod land og fik pigen til skadestuen.

    Det var en trevlig båttur men inte riktigt vad vi föreställt oss. Det stod i beskrivningen ex snorkling, men det fanns ingen utrustning ombord och inte heller något direkt snorkelställe. Men det var trevligt badstopp, hoppa från båten, besök i en fin kyrka och sedan glasbotten på båten var häftigt att se igenom.
