Nice little trail I always did along with other trails. Very shady and can be done any time. It drops off Bear creek with a little drop in elevation and is almost entirely in the shade.. The 1st right is a trail that goes up to Briones res. A little farther up towards San Pablo on a day I was solo I got within 10' of a half dozen deer. Memorable day...
