FULL SUMMARY

The “East Bay” is the eastern region of the San Francisco Bay area and includes Alameda and Contra Costa Counties.  By far the most significant and popular climb in the East Bay is Mount Diablo.

General Information

Mt. Diablo is a very popular East Bay State Park that offers many hiking trails, camping options, and excellent views of the Bay Area and east towards the Sierra Nevada Mountain Range.  It is no coincidence that Diablo is “Devil” in Spanish, an appropriate name for this lengthy and challenging East Bay bike climb.

There are 360 degree views from the visitor center and observation deck at the mountain’s summit.

There is a historic beacon tower and museum-like visitor center at this bicycle climb’s finish.  “Mount Diablo is the starting point for the establishment of land boundaries throughout most of Northern California and all of Nevada. The summit is the location of the "Initial Point," the north/south meridian, and east/west baseline intersection point that is the basis for most property boundaries” (see history article).

This is a fairly remote East Bay climb that travels through the Sunol Regional Wilderness Area. We are on a one lane road the entire climb that has very little traffic on it.  Most of the climb is through Coal Mine Canyon and has a canopy of tree coverage much of the way.  There are no distant views along this climb other than briefly at the top.  This ascent is an attraction for its challenging grade (particularly 1.2 miles from mile 1.7 which averages 14.2%).   The roadway is single lane and has more the feel of a bike lane as it winds its way through the canyon to a locked gate where the road turns to dirt at the top.
