The ride: Start at the gate in the parking area. The trail is real easy to follow, all turns are marked, and it is easy to follow the bike tracks. The trail is mostly single track, with a short bit of fire road at the beginning. The trail is well designed, with a couple fast downhills and a couple nice rock gardens thrown in. If you want to ride more than the 6 miles, when you get to the turn-around point in the SRA, ride up the road 1/4 mile and ride the Salmon Falls (Darrington) Trail also.
Take Hwy 50 east from Sacramento, exit at Folsom Blvd exit, and turn left on Folsom Blvd. Continue on Folsom Blvd to Green Valley Rd. Turn right on Green Valley Rd. Stay on Green Valley Rd until Salmon Falls Rd. Turn Left on Salmon Falls, continue on Salmon Falls Rd for 3 or 4 miles, Trailhead is on a sharp left hand turn, on the left side. If you get to the Salmon Falls Bridge, you went to far. Parking is in a little parking area, or alongside of the road. Alternately you can continue up the road and park in the SRA parking, and start the trail from that side.
