The west of the Antelope Valley within the Angeles National Forest is the setting for the Grass Mountain Trail. Starting at the south of the Lake Hughes settlement, this trail is a rough graded dirt road that slowly starts ascending the chapparal hills.

You drive roughly for about 1.1 miles during which you find yourself on the same route as the Tule Ridge Trail. Further on it divides and travels to South Portal Canyon. At this place the Grass Mountain Trail goes around the north-eastern side of the Grass Mountain. You can walk up the short spur to the top of the Grass Mountain from there. This is a great spot to rest a while. There is a large open are surrounded by Coulter pines.

From here you can choose to move towards the south of this trail or move further up.

If you want to discover more, you can take the trail upwards. This goes around the top of the ridge, passing by the Bouquet Canyon Road. You can get a good view of Bouquet Lake towards the south.

If you choose to descend, this trail moves southwards. You soon cross San Francisquito Canyon Road where you pass by the Green Valley Ranger Station after about 0.8 miles.


The Grass Mountain trail can be closed to public due to bad weather or forest fires which are frequent. Check with the Forest Service prior to doing this trail.
