Encompassing four distinct forest types, El Yunque is home to 240 species of tropical trees, flowers, and wildlife. More than 20 kinds of orchids and 50 varieties of ferns share this diverse habitat with millions of tiny tree frogs, whose distinctive cry of coquí (pronounced "ko-kee") has given them their name. Tropical birds include the lively, greenish blue, red-fronted Puerto Rican parrot, once nearly extinct and now making a comeback. Other rare animals include the Puerto Rican boa, which grows to 7 feet (2.1m). (It is highly unlikely that you will encounter a boa. The few people who have are still shouting about it.)
El Yunque is the best of Puerto Rico's 20 forest preserves. The forest is situated high above sea level, with El Toro its highest peak. You can be fairly sure you'll be showered upon during your visit, since more than 100 billion gallons of rain fall here annually. However, the showers are brief and there are many shelters. On a quickie tour, many visitors reserve only a half-day for El Yunque. But we think it's unique and deserves at least a daylong outing.
