West Ridge Route
Topo of the West Ridge

Looking at Grass Mountain in Los Padres National Forest from a distance, the west Ridge looks quite tame. But when you actually hike the trail, your endurance and resolve are thoroughly tested. There are no rocky sections, nor are there any switch backs. In short, West Ridge of Grass Mountain is no walk in the park. After the initial three quarters of a mile, the steepness of the trail becomes unrelenting. You gain over 2000 feet in only 1.2 miles. Since most of this mountain is covered by chaparral, your choice of routes are limited. The West Ridge, oddly enough stays free of chaparral and is the most reasonable route to the summit. Be prepared for a difficult hike with great views. During the summer months the creeks are bone dry and the area is quite hot. Carry three quarts of water. The return can be confusing. So, carry a compass or a GPS and make notes on the way up.

Getting there, The Trailhead, Red Tape

Grass Mountain
Hiking Permits Box
From the city of Santa Barbara on the southern California coastline, take Highway 154 and drive for seven miles to San Marcos Pass. Drop down the back side and drive 14.6 miles to the junction with Figueroa Mountain Road at the town of Los Olivos. Take a right here and drive five miles to Midland School.

Grass Mountain trail is located within the Midland School property. You need to get a permit to enter the area.

Drive into the school and find the box marked "Hiking permits." You need to fill out a permit form, leave a copy in the box and carry one with yourself. Get back onto Figueroa Mountain Road again and drive another two miles up the road. The road makes a sharp turn to the right and crosses a cattle guard. Shortly after the cattle guard there is a gate. You can park here, but not too close to the gate. The trailhead is right across from the gate. There is also a large pullout just before the sharp turn on the road and the cattle guard.
