The hike begins through low-elevation forests and follows the remnants of an old community-built trail from the 50’s and 60’s. From there the trail winds through old-growth cedars that are estimated to be more than 800 years old, and through spruce and subalpine fir stands with occasional views over the Robson Valley to the south. The cabin itself looks out across the valley between Red and Green Mountain and was refurbished in 2022.
Trail is in generally good shape with the occasional blowdown and brushy sections.
