From Iron Springs Rd, the trail begins climbing immediately. The trail is steep in spots with many water bars. The vegetation is mostly low pinion-juniper scrub and the slope faces south, so it will be hot on a summer afternoon.
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.
Much of the terrain that this trail traverses was burned in 2013 by the Doce Pit forest fire. Use caution and be alert for erosion.
This trail meets up with several other trails that can be combined for a varied experience. Clark Springs 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.
