This is a 6.3-mile trail near Mount Waterman California, generally considered a moderately challenging route, it takes an average of 3 h 14 min to complete. This is one of the most enjoyable hikes around the Los Angeles area. The hike moves through a pristine wilderness area along a magnificent section of the Pacific Crest Trail. Fragrant pine and cedar forests loom overhead with the soothing sound of trickling water in Cooper Canyon creek just dazzling the senses. After crossing the creek in Cooper Canyon you will see a large waterfall up to the left which is accessible by using a steep trail down to a large pool at the base. Cooper Canyon Falls just roars in the springtime! Continuing on, soon you will see Mt. Williamson emerging in the background and you will arrive at Little Rock Creek, a great place to have lunch before starting the final ascent up the trail. On the way back up you will encounter Rattlesnake Spring, a lightly cascading waterfall that sounds like a soothing indoor fountain and a much-needed respite as you grind your way back up to Eagle's Roost parking area.
This is a very popular area for hiking and running, so you'll likely encounter other people while exploring. The trail is open year-round and is beautiful to visit anytime. Dogs are welcome, but must be on a leash.
