Magruder Corridor Historic Mining Road

The Magruder Corridor carves through the largest roadless area in the lower 48, connecting Elk City, Idaho to Darby, Montana via a historic pack trail turned mining road. This 100-mile route crosses the Continental Divide twice, threading between the Frank Church River of No Return Wilderness and Selway-Bitterroot Wilderness. The notorious Magruder Pass sits at 8,000 feet, where weather can turn deadly even in summer and snow lingers into July.

This is serious backcountry requiring high-clearance 4WD, recovery gear, and self-sufficiency for 2-3 days. Sharp rocks, narrow ledges, and creek crossings demand mechanical sympathy. Best tackled July through September when snow clears. No fuel, no cell service, no bailouts for 100 miles. What you get is pure wilderness solitude and the satisfaction of crossing one of America’s most remote public roads.
