The Rowher Trail is in Los Angeles County, California and Angeles National Forest. It travels through the Rowher Flat OHV Area up towards the ridge, where it meets Sierra Pelona Trail. It is 4.1 miles long and considered "Most Difficult".
Exit the 5 freeway at Valencia Blvd and make the turn to head west into Valencia at the bottom of the off-ramp. After a few miles you will come to Bouquet Canyon where you need to make a left turn. About 8 miles along Bouquet Canyon you'll see the Welcome to Angeles Forest sign and pass a couple of ranger stations. At about 10.2 miles road 6N07 goes up to the right and back toward the way you just came in.
