Sadly the excellent paved car-free bike trail is interrupted here by a freeway for which they didn't build a bike bridge or underpass. Hope more people lobby to correct this to save lives by avoiding the busy road, and make biking more attractive.

Camino Diablo Road is a serene, pretty, and quiet country road. You effectively use this road to shortcut a visit to the intersection of Vasco Road with Marsh Creek Road. It comes as a welcome break from the heavy traffic and trucks on the last portion of Vasco Road covered on this route. After 3.5 miles on this road through grassy, treeless terrain, Camino Diablo merges onto Marsh Creek Road, which makes up most of one side of this roughly triangular ride route and takes you all the way to the beginning of Morgan Territory Road.
