I give it a 5 star really a top tour was on my own even - Experience: Blue Caves of Zakynthos Tour Trip During my holiday on Zakynthos one of the highlights was definitely the tour to the Blue Caves. We left early in the morning from the port of Agios Nikolaos with a small boat, which gave a more intimate experience than the larger tourist boats. As soon as we got near the caves, the view became truly spectacular. The rock formations along the coast were rugged and impressive, with colors ranging from white and gray to deep orange. But the real magical moment came when we entered the caves: the sunlight reflected off the water in such a way that it created a bright blue glow – almost unreal beautiful. The name “Blue Caves” is really not an exaggeration! The captain made us stop at several places to swim. The water was crystal clear and perfectly cool on a hot day. We snorkeled around the caves and saw all kinds of fish, and even some sea urchins on the rocks. What I also really appreciated was the explanation given by the guide about the geology of the caves and the history of the island. You noticed he was proud of his island and his enthusiasm was contagious. Tips for other travellers: • Go early in the day to avoid crowds and have optimal sunlight in the caves. • Bring swimming gear, an underwater camera and water shoes. • Choose a smaller boat for a more personalized experience and access to narrower cave entrances. Final verdict: An unforgettable experience not to be missed while on Zakynthos. The combination of natural beauty, adventure and relaxation makes this a perfect day trip.

Excellent trip to turtle island and Keri caves - Today we joined the ship of captain Alexander (the great) and what an excellent tour guide he is. He showed us the wonderful turtles and maneuvered his boat professionally so we could spot the turtles and take pictures. Afterwards we saw the amazing Keri caves which was spectacular and worthwhile to see. We recommend this trip.

Awesome short tour! - This tour was amazing. Alex, the captain, made it what it was. He was friendly, funny throughout, very informative yet personable, even keeping the boat still when he noticed my wife and I trying to take selfie with cameo island in the background! The views are beautiful. Alex drives through the caves, stops at key places for photos. Within 10 seconds of the boat departing, we’d already stopped as a turtle was swimming past us. We stopped at one of the cave spots to swim in the water. This is a really nice 20 minute stop where you can jump from the boat. Alex was really relaxed and chatting to everyone and helping with photos. The stop at Marathonisi (Turtle Island) is great. Alex gives you an hour to sit and sunbathe or take a dip. Strongly recommend!!
