This is a beautiful natural water park, very good snorkeling place. We took the combination tour of Tulum and Xel-Ha, and we felt that we're not given enough time to enjoy the activities in Xel-Ha. We enjoyed snorkeling in the inlet, saw many colorful fish, the water was so clear. This is an all-inclusive park and our entrance fee included: locker, towels, drinks, buffet lunch, showers and life jacket. If you'll use their snorkeling equipment you need to deposit $20. Inside the park, we took the Sea Trek tour, they let you wear a diving helmet for 45 minutes at the price of $45. We felt this was a waste of time and not worth it, the water was full of silt, saw only a few fish and touched the stingray. No big deal, just skip this activity. They also offer swim with the dolphins and snuba, we didn't try any of this coz we're pressed for time. The food inside the park was really good, lots of choices at the buffet, worth the price. If you want to go to Xel-ha, remember to bring your own bio-degradable sunblock lotion, that's the only that they allow you to use. They check bags before they let you enter. I suggest that you spend a full day in Xel-Ha in order to enjoy all the activities this park has to offer.
