The main geographical feature of the forest reserve is Monte Guilarte, which is Puerto Rico's 7th highest mountain at 3,950 feet (1,204 m) above sea level.

While Monte Guilarte is located in the municipality of Adjuntas, the forest's borders also include parts of Guayanilla, Peñuelas and Yauco.

The reserve was intended to be a wildlife preserve for the conservation of numerous plant and animal species found in the area but also for recreational purposes.

[1] The forest reserve is open during daylight hours and offers opportunities for hiking, birdwatching and cabins.

There are seven cabins (with room for 4 guests) available, and reservations must be made in advanced by contacting the Puerto Rico Department of Natural and Environmental Resources.
