Baylor Pass Trail. Aguirre Spring Campground has two designated trails - Pine Tree trail I hiked on Monday and the Baylor Pass National Recreation Trail I hiked yesterday. Baylor Pass trail is somewhere (literature varies) between 5 and 6 miles one way and goes over Baylor Pass to crisscross the Organ Mountains. It was an easy hike as the pass is only about 6500 feet and the steepest vertical gain (from the east side) is only about 1500 feet; the desert southwest is beautiful. These hikes are slowly helping to strengthen my hiking bones and get back in shape.
