The Overflow Trail starts from the cement flume used as an overflow from DeSabla reservoir and turns in to a steep rocky descent down to Indian Springs Trail.
The Indian Springs Trail is multi-use single track offers a fast steep rocky descent with lots of nice views of the canyon. The trail is in good shape and built well although the bushes are overgrown on the lower half. Once you reach the bottom the only way out is to hike all the way back up.
With a Black Diamond difficulty rating across both trails, expect and enjoy a hard, physical ride down almost two miles and a 1,800 feet descent.
