Go along Purisima for about 150 feet, then take a left onto a wooden bridge.
-After the bridge take a right and get onto Harkins.
-After a while you will come to a jeep trail, take a left.
-About half a mile down you want to turn left onto Whittemore Gulch, keep your eyes open.
-This brings you back to the bridge that you crossed earlier. If you want more riding why not add the Borden Hatch to Grabtown Gulch loop.
How to get there:
Get onto HWY 92 and turn left onto HWY 1, then take another left onto Higgon-Purisima Creek Rd. Keep going straight through the fork, the parking lot is about 2 more miles on your right.
Helmets required, there are horses, and the trail is closed during the rainy season.
