Semi-submarine boat trip

4.3/5
90 reviews

If you fancy taking a look under the water – without having to get your hair wet – then this glass-bottom boat trip from Agios Nikolaos will give you the glimpse you were looking for. You'll glide out into the bay aboard a semi-submarine for a look at the sea creatures and rock formations you might not ordinarily see.

Hop aboard this specially-designed boat, which features windows beneath the surface. Kids and adults will have a great time spotting the likes of caretta caretta sea turtles and multi-coloured fish darting around the rocks. The other fascinating thing is the underwater geology, with all shapes and sizes of rocks and seabed to admire.

Information boards are available on the boat, too, so you can brush up on your knowledge of local wildlife. And once you've seen enough below deck, you can sit on the top deck and watch Agios Nikolaos come into view as we head back into the port.

    A great experience overall, you are crammed on a little, especially when in the underwater viewing area. The boat is a catamaran so if you get chance to choose where you sit, try and sit on the outside looking into the deeper water for a better view. The inner seats face the other hull so part of the view is restricted, you still see the fish but only by looking down. Looking straight ahead your view is restricted by the other viewing hull. Overall very good and pretty good value for money.

    Great boat, saw lots of fish, lovely to spend time on the top of the boat along the coast too. Staff on the boat didn’t communicate very much, was all automated but was still interesting information.

    Gefallen hat uns die Freundlichkeit der Mitarbeitenden und die Sicherheit an Bord. Weniger gut fanden wir, dass wir unter Deck aufgrund der Platzvergabe fremdbestimmt waren und dadurch wenig flexibel. Bei anderen Touren dieser Art konnte man selbst entscheiden, ob man runter geht oder oben ist. Gerade mit Kindern ist es schwierig. Die Infos auf verschiedenen Sprachen waren gut, aber manchmal zu viel. Es gab kaum ruhige Momente nur zum anschauen.

    Wer an den Steinküsten bereits geschnorchelt hat, dem sind die meisten Fische bereits bekannt. Ansonsten ein sehr schöner Blick in die Unterwasserwelt. Durch das Anfüttern kann man eine Menge Fische sehen.
