Discover the abundant flora and fauna in a sprawling national forest by browsing interactive exhibits before experiencing the nature firsthand at several extraordinary wilderness sites. El Yunque National Forest is the only rainforest in the U.S. National Forest System and it is truly spectacular. Upon arriving, you will explore the welcome center El Portal, which is constructed of natural materials that beautifully blend into the landscape. There you will see enlightening exhibits and an entertaining video that describes the environment. Continuing on, you will drive deeper into the rainforest and pause for photos at Bano Grande, a deep pool that flows over a masonry dam built in the 1930s. For a different perspective of the rainforest, you will climb a nearly 7-story observation tower that offers panoramic views of the lush foliage and mountain peaks. Nearby, you will find La Coca, a waterfall that plummets down a sheer cliff into a pool at the bottom.
