Thomas Hunting Grounds is an 11.6-mile straight-through dirt alternative to Highway 38 that contours the hills above Mill Creek, passing Morton Peak, Mountain Home Peak, and Constance Peak in about an hour. Frequent turnouts offer amazing scenic views of the Inland Empire. The route is easy and beginner-friendly. Scattered rocks about golf-ball to softball size are mostly avoidable, and any stock SUV or truck can make the drive. Multiple side spurs provide dispersed camps for 4–6 vehicles; sites are first-come, first-served, and some have established fire rings. Per the U.S. Forest Service, a California Campfire Permit is required for any fire use, including campfires, charcoal BBQs, and gas stoves, and only street-legal vehicles are allowed.
