This trail is a nice loop that is smooth and shaded for the bottom half, but it does get a bit steeper, rougher, and more exposed as you climb to the top. Alternatively, you can continue on the Contra Costa Feeder Trail and take the loop in the opposite direction for a less strenuous ride.

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.

The path is scenic, with fantastic views that take you across the hills of Almond Ranch and into the adjacent Sky Ranch territory. The trail has a few brief, steep areas that provide an exciting challenge as you climb. Taking this route in reverse is also an exhilarating experience as you navigate through a series of grade reversals put in place to drain water during heavy rains.
