El Yunque National Forest, formerly known as the Caribbean National Forest is located in the rugged Sierra de Luquillo, 40 km southeast of San Juan. The Forest contains rare wildlife including the Puerto Rican Parrot, which is one of the ten most endangered species of birds in the world. El Yunque is less than an hour's drive from San Juan, and there's road access to the reserve. We drove out in the mornings from San Juan to visit the rain forest. It is a nice drive and in the afternoon we retired at Luquillo beach, which is nearby.
