The Paradise of Zakynthos - The paradise of Zakynthos is contemplated with a three-hour tour, where you can admire the caves of Keri, with stop and bath, and the golden beach of Marathonisi where the caretta turtles nest.

Great family day out - I was worried about going on this trip with young children, especially my 3 year old, but they loved it. Our Captain quickly located some turtles, which everyone loved. We then explored the area around Keri caves and stopped for a swim in some beautiful water. We then stopped at Marathonisi for an hour. Everyone loved it.

Turtle Sighting Glass Bottom Boat - Lovely trip. Great value. Saw the turtles. Captain drove through the cave which was exciting. We spent 90 mins at the beach which meant less time at the caves - which was unfortunate for snorkelling fans. Moved to later boat with an hours notice but not a problem as places for coffee and breakfast.

Opportunities for great pics. - This was a nice trip. I think the captain could have talked more and a drink included in the price would have been good. Kids really enjoyed it. We saw 3/4 turtles.

Disappointed - It was okay, but after one turtle came up, the boat raced away to the next part. We were let go for a full hour on the toad island, but there was really nothing to see, was only very hot and nowhere shade. We were also back fifteen minutes early. I was able to take beautiful pictures, but had imagined more of them.

Terrible - We thought it was at the beach we picked up the boat no one explained that we had to walk over rocks and through the sea. Got half way there and gave up. We did see the boat go out and we're glad we didn't get on it because it was cramped packed.
