Park in the big dirt area before the gate, at the end of the public part of Amber Fields Drive. From here, take the trail north: you can keep left next to the horse pasture fence, or cross the tracks to the trail on the other side. Since there's separate trails on each sides of the tracks, you can make this into a loop of sorts. Nice views all the way to the Sacramento Valley within a couple miles. The early part has a good amount of shade, less later on. Rolling hills. One mysterious car wreck. Best viewed from March through May for flowers.
