In recognition of the sensitive nature of Rio Grande cutthroat populations, the New Mexico Department of Game and Fish has placed a two fish possession limit on these trout. The San Pedro Parks are broad open meadows amid the spruce and fir forest. The San Pedro Parks lie just to the east of Cuba, New Mexico in the Santa Fe National Forest. Easy to reach from Santa Fe and Albuquerque, the wilderness sees moderate usage on summer weekends. Trails approach the parks from all directions, but those to the north, west and east require long, jolting drives on rutted roads to reach the trailheads.
Most hikers come into the parks from the south.
The easiest access and most popular trailhead is for the Las Vacas Trail near San Gregorio Reservoir on Forest Road 70. Reach the trailhead via State Road 126 out of Cuba or the village of La Cueva, which is north of Albuquerque on State Road 44 and State Road 4. Take State Road 126 about 30 miles from La Cueva, most of which is unpaved, but is passable to all vehicles except in winter and after heavy rains. From Cuba, take State Road 126 about six miles, all but the last half-mile paved. Turn onto Forest Road 70, reaching the trailhead in three miles.
