Mount Jumbo (officially known as Mount Bradley) rises dramatically above the town of Douglas, just across Gastineau Channel from downtown Juneau, Alaska. Mount Jumbo is part of the Tongass National Forest, the largest in the nation, which covers most of Southeast Alaska. The trailhead begins just above sea level near downtown Douglas and rises steeply to the summit at 3,337 feet. The trail is well defined but very steep and technical in places.
From downtown Juneau, take the Douglas Bridge across Gastineau Channel to downtown Douglas. In Douglas, go right on E Street, then left on Fifth Street to the trailhead, in the 300 block.
Mount Jumbo can be climbed year-round. Skiing is popular on Mount Jumbo but be aware of avalanche conditions. Snow can be found on Mount Jumbo well into July. The Juneau area is extremely wet, so bring your raingear.
Permits are not required to climb or camp on Mount Jumbo.
Flat tent spots are difficult to come by on Mount Jumbo. Do not expect to find adequate camping areas until you reach treeline, where a few level spots can be found. Once above treeline, camping is not possible until you reach the summit where some level ground can be found.
