Route Details
In 1863, an Elk City merchant named Lloyd Magruder was brutally murdered by bandits near the Selway River while returning from a gold trading trip to Montana. The suspected bandits were eventually caught and hanged in Idaho Territory. The Magruder Corridor, over 100 miles long, traverses some of the most remote wilderness in the lower 48, flanked by 3.5 million acres of designated wilderness to its north and south. Originally a Nez Perce trade route, the Civilian Conservation Corps (CCC) improved the original footpath into a single-lane dirt road in the 1930s. In recent years, the legend of the Magruder Corridor has attracted overlanders and adventurers seeking to immerse themselves in some of the most pristine and remote wildlands of the Pacific Northwest.
While the trek along the Magruder Corridor makes up less than a third of the total Magruder Discovery Tour, the vast wilderness sets the character for much of this rugged and remote overlanding route. The Magruder Discovery Tour begins at the eastern end of the famed Magruder Corridor, which cuts through the ultra-remote Bitterroot Mountains. The Magruder Corridor itself is a tame, single-lane dirt road. However, if you've got a 4x4, be sure to stop by some of the discovery points like Hells' Half Acre Lookout, Magruder's Ranger House, Burnt Knob Lookout, and Green Mountain Lookout. Some of these side trips require a lifted 4x4 (more info can be found in the "Alternative Routes" section). Camping along the Corridor is largely relegated to dedicated campgrounds. While it's a bit out of the way, our favorite place to camp is Paradise Campground at the confluence of the Selway River and White Cap Creek.
As you wrap up the Magruder Corridor and head south, most folks will want to stop in Grangeville to refuel. This next leg takes travelers to the eastern edge of the Clearwaters, a subrange of the Rocky Mountains. Here, the Salmon River (a key discovery point) is the major waterway through this mountainous region of Idaho. The vast majority of roads here are similar in nature to the Magruder Corridor: tame, graded, and typically suitable even for a Subaru. The out-and-back drive to Square Mountain Lookout (discovery point) affords impressive views of the surrounding Clearwater Mountains and the Seven Devils Mountains (discovery point) to the southwest. Follow the track down the mountain to the banks of the Salmon River. But don't get too comfortable, as you'll be headed right back into the Clearwaters—this time to Slate Point Lookout (discovery point), another viewpoint with equally impressive vistas.
From Slate Point, you'll follow the spine of a ridgeline better known as Nut Basin Road. A few hundred yards off the main road, you'll find the Nut Basin Viewpoint (discovery point). This viewpoint not only offers fantastic scenery but also the remains of the old fire lookout that once stood atop this peak. Continue along the graded dirt road down the mountain and up and over to Chair Point Lookout (discovery point). From Chair Point, the route follows the banks of the Salmon River (discovery point), crossing the historic Manning Crevice Bridge (discovery point). This historic suspension bridge, built in 1938 by the CCC, is a favorite stopping point and photo opportunity for those passing through. This stretch of the Salmon also features a number of riverfront campsites.
Heading south along French Creek Road, you're officially on the final leg of the route. Glacier-carved peaks rise to the east as you close in on Upper Payette Lake. Once you reach Payette Lake (discovery point), be sure to visit the historic and vibrant downtown of McCall (discovery point), which is filled with shops, restaurants, historic buildings, and more. The route concludes along the West Mountain Jeep Trail (discovery point). For those seeking more moderate terrain, West Mountain is your ticket! This bumpy and loose track climbs into the forest and features impressive views of Payette Lake and the surrounding mountains. Eventually, you'll find yourself back on pavement and at the quaint lakeside town of Cascade, the route's official terminus.
