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!"
