Excellent organization! Very friendly staff! :) We even drove a detour to see the turtles. Drop-off and pick-up were flawless. We would definitely use them again!

We had booked to go on the glass boat. But because we were there in early May, it was not available yet. So we got to go on a speedboat with 6 others! It was a great experience with a very good experienced guide. 100% worth the money!!

Absolutely fantastic in one word: 3 hours is enough to see everything properly, and we even saw turtles – what more could you ask for?

Great day! The program is well put together, an effort is made to find turtles. We swam wonderfully and enjoyed the beautiful surroundings. And... we also saw a turtle, despite it not being the right season. If you have the chance, sit at the front of the boat, wonderful! The captain makes an effort for his passengers, despite the fact that we were of course number 20,000!

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