Length: 8.1 mi • Est. 4 h 17 m
The trail starts out very easy with well maintained walking trails. As you progress deeper and higher the terrain increases in difficulty; to the point of being slightly technical. The trail gets fairly challenging on the last mile or so before summit. Beautiful scenery from start to end. Vast meadows sprawling with wild flowers to forests with towering evergreens to rocky boulders of great size. There is a $5 fee for parking.Show more

This in-out hike is a portion of the more popular Mt. Sanitas & Sanitas Valley Loop. It is the more rugged and quicker route to the summit. Highlights include rock scrambling (if desired), a steady ascent, projected outcrops, and a "desert-like" baked earth terrain. When the parking lot is full, designated roadside parking is allowed.
