From Interstate 5 in Burlington take WA 20 (North Cascades Highway) towards Sedro Woolley. Drive 47 miles to Marblemount and then get off on the Cascade River Road. Take this for 22 miles to a turnout (elevation 3,200 feet) beneath the impressive Northeast Face of Johannesburg Mountain.
Follow the climbers trail (originally a road to the Diamond Mine .75 miles above) to the vicinity of the mine site and then traverse open slopes. The climber’s trail is wiped out due to a large avalanche slide from Spring 2002. Continue North for approximately a half mile and cross four streams. A switchback trail leads to a moraine at 5,300 feet where multiple campsites and a compost toilet are located. a second camping area is located at 6,400 feet but remains snow covered until later in season.
Permits are required for overnight trips in the North Cascades National Park. For information call the National Park Service Ranger Station for the North Cascades National Park in Marblemount (360)873-4500.
