Little Granite Mountain Trail #37

Trail Description: Little Granite Trail #37 passes through open chaparral as it winds around the west flank of Little Granite Mountain. Outcrops of granite bedrock have weathered away into fantastic shapes that loom over the trail. It is not uncommon to see wildlife in this area, including snakes, lizards, small mammals and signs of other, larger animals. As the trail gains elevation there are stunning views in all directions. The panorama includes the Sierra Prietas, Sugarloaf Mountain, and of course, nearby Granite Mountain.

Notice: Visitors are asked to be alert and stay on existing trails when recreating on Granite Mountain as the area recovers from the Doce Fire of 2013. Soil erosion has occurred on portions of the trails, thus exposing more rock, and cross-country travel increases the possibility of encountering rolling rocks, stump and root holes, falling trees, and loose soils from rains.  


This trail meets up with several other trails that can be combined for a varied experience. Clark Spring Trail #40 descends along a riparian corridor to the Granite Basin Recreation Area. Farther along, Upper Pasture Trail #38 comes in from the west. The trail ends at Blair Pass and Granite Mountain Trail #261, which enters the Granite Mountain Wilderness. The use of motorized or mechanized equipment, including bicycles, is prohibited in the wilderness area.

This trail is open to hikers, horseback riders, and mountain bicyclists. Please be considerate of other users—slow down and know when to yield the trail. Refrain from using horses and bikes when the trail is wet.
