The Naguabo Infinity Pool Trail plunges you deep into a lush rainforest, offering a raw and adventurous experience. Expect to navigate through mud, over slippery rocks, and across fallen trees, with the added thrill of using ropes and ladders on steep ascents. The journey culminates at the stunning Infinity Pool, a natural highlight that provides incredible panoramic views and a refreshing, cool swim after your demanding trek.
Despite its relatively short 3.4 miles (5.5 km) and 299 feet (91 metres) of elevation gain, this route is far from easy, often taking closer to 1 hour and 30 minutes for the most agile. It's crucial to avoid hiking during or after rain due to the extreme danger of flash floods and slick surfaces; this is not a trail for beginners or casual strolls. Given the lack of cell service and tricky navigation, an offline map or a local guide is highly recommended.
This trail stands out as a challenging alternative to more accessible El Yunque trails, offering a unique blend of natural beauty and physical exertion. It's located in the southern part of El Yunque National Forest, near Naguabo, and notably, it doesn't require an entrance fee. However, be aware that the trail reportedly crosses private property, adding another layer to its adventurous character.
