El Yunque Rainforest is the only tropical rainforest under the protection of the US Forest Service and also the largest nature reserve in densely-populated Puerto Rico. It is situated in the mist-wreathed Luquillo Mountains where year-round precipitation ensures lush, green landscapes and a healthy diversity of animal life. This includes mongooses, non-venomous snakes, the rare Puerto Rican Parrot and the Coqui frog whose distinctive croak provides El Yunque’s soundtrack.
