A nice single track descent (or climb) that can be accessed from the ranch, Lower Aliso Canyon, or a split off Bane Ridge. This trail offers nice scenery, but can be a bit steep and exposed in the northern portion. The trail forks about halfway to Lower Aliso Trail which hooks up to Lower Aliso Canyon and Faultline Trails. Past this fork, the trail becomes much mellower with gentle rolling bumps until the end of the trail which used to have a bridge, but is now a walkable creek crossing.
