We just got back from a Carnival Cruise and stopped in Cozumel, we were looking for a great zip lining place, it was our first time zip lining! We found Ecoparque and it felt very safe and we were very well taken care of! The guys explained all of the safety lines and they only had two rules: 1) have fun and 2) follow the rules. At one point atop of the tower you can look out and see all of Cozumel and the cruise ship! It was beautiful scenery and all in all a great experience!! Definitely would recommend! I do recommend that you bring some extra cash, they take a lot of photos so that you don't have to bring your phone in case you drop it, break it, etc. Unfortunately we didn't bring any extra cash to buy pictures, but we do have our great memories from there! Can't wait to go back!
