Small boat, plenty of time to swim, and the skipper did his best to locate the turtles for us.

Very fun for the family, you see the whole the whole island and get three 30 minute swim breaks. Good price and great time.

Rented a boat, everything was well arranged. The price is comparable to other providers. Tip: go at 9:00 AM (not in the afternoon). It is even less crowded at the counter in the morning (and on the water too!).

This experience was awesome, the staff very kind. We rented a boat without any license and had fun while zooming through the waves.
