Distant sunset from the Briones - Mt. Diablo Trail
At the bottom of the steep downhill end of the Ridge Top Trail, the Briones - Mt. Diablo Trail and Costanoan Trail meet. Turn right on the portion of the Briones - Mt. Diablo trail that bends back northwestward, doubling back below the Shell Ridge formation that you just descended. Continue along this valley floor.
On this valley trail, the richly hued sunset reaches its final burst in this TrailPhoto, leaving the surrounding hills in silhouette.
Continuing on the Briones - Mt. Diablo Trail, you'll soon pass by Fossil Hill Trail on your left. Stay on the Briones - Mt. Diablo Trail to the junction near the school. Retrace your original track back to Kovar Trail and the trailhead (easier to do in full daylight!)
