I just hiked the Oursan Trail, on the north side of Briones Reservoir, last Saturday. This is a really nice, up-lifting hike in the fall when it’s a little cool (60’s) and you want to be in the sun. Just make sure the trail has had time to dry out from any recent rain and isn’t too muddy. You’ll love all the views of Briones Reservoir shimmering in the sun!
EBMUD is considering opening up some of their trails, like Oursan, to mountain bikers. Here’s a link to a recent article in the CC Times.
