Trailhead: Dawson Saddle
Mt. Lewis is a comparatively small bump accessed via a steep use trail across Angeles Crest Highway from the trailhead leading to Throop Peak. I suggest hiking to Mt. Lewis first as a warm up for the longer portion of the hike leading to Throop Peak.
Trail: Steep use trail from Dawson Saddle to Mt. Lewis and back followed by hiking to Throop Peak from the trailhead across Angeles Crest Highway.
