Mount Harkness Professional Guide
Detailed Trail Description from our Guidebook
"From the lookout atop Mt. Harkness, snow-capped Lassen Peak and the rest of the peaks along ancient Mt. Tehama’s rim seem close enough to touch. The impressive vista extends far beyond the park boundary, encompassing an expansive section of the northern Sierra and southern Cascades. Although the climb is stiff, the trip is short enough that just about anyone in reasonable condition can manage it.
Unlike most fire lookouts today, the Mt. Harkness lookout is still staffed, so plan on a friendly welcome from the resident park employee. As with all high peaks, avoid the upper slopes when lightning threatens. Thanks to the fine network of connecting trails within the park, hikers with extra time and energy can alter their return by following a loop along the south shore of Juniper Lake back to the trailhead."
