swimming in the "caves" of keri is of little interest, some fish are attracted by the bread... nice island beach but it is hard to believe that the area is protected! to finish a turtle attacked by 10 boats around it ... try to find some by yourself while snorkeling, the encounter will be much more magical! (this is what happened to us)

The trip itself was really nice. Just keep in mind, that was our impression, that the only turtle we saw is trained on the tourists. The boats gather around one individual and lure them out of the water with their horns. Private boats are being pushed out by tour boats. Otherwise very nice tour with nice impressions. What shouldn't have been, the 1 hour stay at Turtle Beach, where masses of white people docked the tourist boats and dumped the tourists.
