Great experience. Booked on the morning of through this website - didn't confirm as they weren't open until we arrived but we rocked up about an hour before our arrival so we could grab some breakfast. They checked us in as soon as we arrived. Would say if booking the morning of your trip dont expect a shuttle from your hotel - just make your own way there - less stress and loads of parking on the sea front and up the hill in the car parks (all free).

Great tour at the end of September, although most of the turtles were already migrating, we were able to marvel at one. The swim stops were wonderful.

Elselien · CoupleNLNetherlands

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!
