Most guides will have you enter the Sobrante Ridge Regional Preserve from Coach Drive in Carriage Hills, but if you enter from the El Sobrante side — the trail head is at the end of Heavenly Ridge Lane — a short hike past the endangered Alameda Manzanita will take you to the top of the ridge, where a selection of pictnic tables awaits you. A view of Mt. Tamalpais lies to the west.
To the east is Mount Diablo, and to the south Wildcat Canyon.
You can descend to Carriage Hills to the north, if you wish.
