Brought to you by the people who manage Xcaret, Xel-Há (pronounced shel-hah) is a natural aquarium made from coves, inlets, and lagoons cut from the limestone shoreline. The name means "where the water is born," and a natural spring here flows out to meet the saltwater, creating a perfect habitat for tropical marine life. Although there seem to be fewer fish each year, and the mixture of fresh- and saltwater can cloud visibility, there's still enough here to impress novice snorkelers.
Scattered throughout the park are small Mayan ruins, including Na Balaam, known for a yellow jaguar painted on one of its walls. Low wooden bridges over the lagoons allow for leisurely walks around the park, and there are spots to rest or swim.
The place gets overwhelmingly crowded, so come early. The grounds are well equipped with bathrooms, restaurants, and a shop. At the entrance you will receive specially prepared sunscreen that won't kill the fish; other sunscreens are prohibited. For an extra charge, you can "interact" (not swim) with dolphins. There's also an all-inclusive package with a meal, a towel, a locker, and snorkel equipment for $65. Other activities like snuba diving, and an underwater walk, are available at an additional cost and should be reserved at least a day in advance.
