A great adventure near Keri - We really enjoyed this excursion! We saw turtles and swam in some of the most beautiful places we have ever seen. There are lots of caves along the way too. Bring your snorkel and mask if you have one, it was super clear and beautiful in the water at the first swimming stop. Highly recommend!

Great value for money - Boat isn't very big which I preferred. Everything was punctual and we enjoyed every aspect. You start off looking for turtles and we managed to see 3 large ones! Then you head to the Keri caves which were beautiful. Then you stop off at turtle island where you can buy food and refreshments. We got to see a lot in the 3 hours. Great value for money

Highly recommended! - Great boat trip with lovely views of the caves and beaches. We didn’t see any turtles, but the trip was still absolutely worth it. The small group made the experience on the boat even better and more enjoyable. The captain was great and took us to the caves when no other boats were there, which made the experience even more special. He also returned to the nesting beach later to check again in case the turtles had appeared.
