North Fork Big Wood River is an easy out-and-back dirt road beginning off Highway 75 and ending at a hiking trailhead for the North Fork Trail. Soon after passing the Sawtooth Visitor Center, a place you must stop and enjoy, the road turns to dirt. The road follows and crosses its namesake river several times. The river has trout and several beaver dams. The road ends at a lollipop turnaround that serves as a hiking trailhead into the looming Boulder Mountains ahead.
There are several established campgrounds and 17 designated campsites along the trail. Murdock Campground can accommodate larger rigs, while Caribou Campground is more suited for tents and smaller rigs. The Cougar Dispersed Camping Area, set in a lovely area off the main road, can accommodate larger rigs and has a vault toilet. Many of the dispersed sites sit directly on the river banks. There is even a dump station and water just east of the visitor center. All camping is first-come, first-served.
