The San Carlos Indian Reservation is very close to the mountain range, with its boundaries being just a few miles east/northeast of the range.[3] The mountains are covered with Ponderosa Pine and white fir and experience cooler weather than the Globe/Miami area, so that they are a popular recreation area in the summer. The maintained facilities include a maintained dirt road that goes all the way to the summit of Pinal Peak, a campsite and recreational area, many hiking trails,[4] as well as some radio towers near both Pinal and Signal peaks (the two highest peaks of the range).
