El Yunque National Forest
El Yunque National Forest is a tropical rainforest in the U.S. island territory of Puerto Rico. This near 30,000-acre jungle is a paradise of winding rivers, cascading waterfalls, ancient petroglyphs, rare fauna (think hybrid tree-dwelling frogs!), and almost 40 kilometers of nature trails.
The area is popular with tourists and can be explored via a variety of tours out of Fajardo and San Juan.
