The El Yunque National Rainforest, or simply El Yunque, is the only tropical forest in the U.S. National Forest System. It's also a particular favorite for vacationers who like to hike, but even if nature really isn't your thing, travelers urge you to make the trip about 30 miles east of San Juan.

Remember to wear layers that can get wet (the highest elevations can receive up to 200 inches of rainfall annually) and pack a water-resistant camera to capture some of the area's splendor. Keep your ears peeled in the evenings, when Puerto Rico's tiny coquí tree frogs begin their serenade.

The forest is still undergoing recovery efforts following Hurricane Maria. Certain trails remain closed (such as La Mina) but other hikes are open and range in difficulty. Angelito Trail, an easy hike that leads you to swimming spots; El Toro Trail, a difficult trail which takes you to the highest peak in the Luquillo Mountains; and La Coca Trail, an extremely challenging and primitive hike, are all open to visitors. All camping is also unavailable at this time. Check the U.S. National Forest Service's alerts and notices website before your trip to know which trails and roads are open.

Travelers agree that El Yunque is a worthwhile daytrip to get out of the busy city. In addition, many travelers also note that they explored the forest on a guided tour, rather than exploring by themselves. Tours can be prebooked on your own, or your hotel's concierge can recommend one for you when you arrive.

Entering the forest is free. You can access the forest from 7:30 a.m. to 6 p.m. daily. Note that the visitor center (El Portal) is currently closed. Visit El Yunque's official website for further details.
