What we did

Bumpass Hell is five miles round trip on the alternate route, and the Dixie Fire opened the first stretch years back, so there is almost no shade where you want it most. Five miles reads fine at the trailhead. A good part of the climb was spent carrying one of us, and where the trail crossed snowmelt we soaked our shirts to carry the cold up the dry part.
