to get there:
From Yolo county, Woodland and Davis, take Highway 16 through the Capay Valley.
Drive up Highway 16 through the Capay valley. Pass the town of Rumsey and continue up the highway. You'll pass Yolo County's three park sites, then cross the county line into Colusa County. Continue on to the intersection of Highway 16 and Highway 20. Head west (turn left) on Highway 20. Continue on Highway 20, heading uphill, past the scenic viewpoint turnout, until the road makes a hairpin turn to the right. The parking area is across the highway at the beginning of the hairpin turn. It is a dangerous crossing, so you may want to head further up the highway until a safer spot, and turn around to go back to the Lynch Canyon parking area.
The parking area has no facilities.
