McGruder Corridor Road_Nez Perce NF

The 101-mile primitive Magruder Corridor Road winds through a vast primitive area in between the Frank Church-River of No Return Wilderness and the Selway-Bitterroot National Forest, from Elk City, Idaho, to Darby, Montana. The trip offers solitude and pristine beauty as well as expansive mountain views. The landscape is much the same as when the Nez Perce Indians and other early travelers crossed the area more than a century ago. The corridor was created in 1980 when the Central Idaho Wilderness Act was passed, leaving a unique road that enables a traveler to drive between the two wilderness areas. There are many great areas to set up camp and explore side trails along the way. Be sure to plan several days for the trip so you can enjoy the countryside. To help safeguard the naturalness of the area, please practice “leave no trace” techniques. Remember that no motorized vehicles are allowed on wilderness trails.
