Follow the left fork, up the hill. This is Forest Road. Follow Forest Road up hill through two switchbacks, until you come to a stop sign. Turn sharply left, and continue uphill another 100 yards. The VTS is on your right.
Parking is limited, and generally crowded.
Generally, parking will be available here. If not, please proceed back down the hill to the first switchback, but go straight through the stop sign. 30 yards past the stop sign, you'll find a large parking lot which almost always has room.
