Shirley Peak is located on the Greenhorn Summit near Lake Isabella, California. Shirley Peak is adjacent to Alta Sierra at Shirley Meadows which is a snow park in the Winter. Trails and roads in the area are often used by hikers, mountain bikers, as well as the OHV community. To climb Shirley Peak one must first follow the directions to reach the parking area on the Greenhorn Summit.

From the parking area(6770') you will see a marker on the East side of the road (as shown in the photo). Just past the marker is a fork in the trail, but take the right fork and stay on the overgrown road. Follow the overgrown road for about .1 of a mile and then climb due Northeast.

As you climb Northeast cross-country amidst dense trees you will cross a paved road, and then a dirt road. The summit (7091') is a pile of rocks, and there is no register there.

The hike is 1 mile round trip with an elevation gain of 321 feet. You can either head down Southwest through the trees the way you came, or you can climb down 1 mile and do Cooks Peak which is on the same ridgeline as Shirley Peak.
