Ria Celestun is one of a handful of breeding grounds for the pink flamingo. A ride in a shallow drafting "lanchon" gets you close enough to see them taking care of their brood.

Explore "Ojos de Agua" in the nearby mangroves and encounter a wide variety of tropical birds and other fauna including spider monkeys.

Celestun is situated west of Merida on the Gulf of Mexico side of the Yucatan Peninsula. It might sound far from Merida, but the ride from Merida's airport takes less than an hour and a half.
