Crossing of two of the best East Bay flat bike trails, one following a former rail line, the other an old canal that still transports municipal water.

Arroyo Del Hambre, Alhambra Valley

Pleasant, mostly shaded road with little midday traffic, though eastbound picking up around afternoon rush hour. Almost unbelievably rural feeling so close to the Bay. Unfortunately long parts without shoulder.

View of Bear Creek

This view of Bear Creek lets bikers peer down into the Bear Creek section of the Briones Reservoir, which has two sources for its water, one source is local and one source is imported.

Little John Cove overlook of Briones Reservoir

Great overlook of the reservoir, along the road as unfortunately the trail around the lake is closed to bikes.

Nice shaded view from the bridge across the creek that fills the San Pablo reservoir, with the help of additional water piped in from Sierra Nevada reservoirs including Lake Comanche.
