Xel Ha (pronounced Shell-Haw) national park seems like the largest aquarium in the world, only you’re in a natural environment and it is a park.
Swimming and snorkeling in the warm protected lagoons and canals offer even the novice a chance to enjoy thousands of brightly colored tropical fish. This can be combined with a walk along the trails and a visit to a small museum.
There are parrots, dolphin shows, hammocks and music, ice cream vendors and of course – rolling beer bars. Everything you need can be rented, there is even an all inclusive entry package that includes meals and drinks along with your snorkeling gear. Xel Ha is a really great place to spend the afternoon after a early morning trip to see the ruins at Tulum.
