In Cancun we went to the Tres Rios, the Eco Park. We weren't sure what to expect and were VERY PLEASED with that excursion, too. We were on the first tender out, since it was one of the ship's excursions. We were taken there (50 minute ride) by Mr. George, our driver and George our tour guide on a luxurious charter bus. Once we got there WOW! We bicycled down to do freshwater snorkeling to see underground rivers - that was cool. (they took excellent care of our belongings and were very professional with the process.) Very different from the barrier reefs the two days before. The jungle grew right over our little river, which was only as wide as a sidewalk! Then the beach was awesome. Kayaking to see alligators - ooohhh. We didn't make time to horseback ride, but everyone looked very happy on their horses. The food and beer at the snack place were overpriced, but an excellent buffet was available at the larger outdoor restaurant. We didn’t try it – all we had done is eat on the ship!!! Did some good shopping there in the park.
