Starting at Black Rock and walking to the North Entrance is the easier direction: most of the climbing comes early, then the route generally trends lower. The first stretch to Upper Covington Flats is about 8.5 miles with roughly 1,180 feet of gain. Farther east it passes Juniper Flats, crosses Geology Tour Road and Twin Tanks, then finishes at the North Entrance. Trail signs and mile markers cover much of the route, but they are not continuous; keep an offline map and pay attention at backcountry crossings. The nearby Quail Mountain summit path is a suggested route, not part of the marked CRHT.
