Also called the Dr Juan A. Rivera Zoo, the Mayaguez Zoo is found off the beaten tourist track in Mayaguez on the east coast of Puerto Rico. It's a world-class establishment and well worth a visit for animal lovers and those passionate about wildlife conservation. Its growing collection of rare and exotic animals include lions, tigers, jaguars, hippos, giraffes and rhinos, as well as many species of tropical birds and large and varied collections of butterflies, amphibians and snakes. Central to the zoo's growth has been a focus on conservation and several native species, including the Andean condor and the Puerto Rican crested toad.
