Sturtevant Falls is one of the most amazing falls within the Angeles National Forest. The trail to Sturtevant Falls follows a prestine creek past era cabins. There is a small pool of water for a quick dip to cool off and relax. This trail can also be offered as an intermediate. Winter Creek Loop is among one of the most popular trails in the San Gabriel Mountains.
The grade is pretty consistently around 10%. This is some nice singletrack and an alternative to the other trails around.[Source: MTB Project]
