From the North and the South take your best route to Hwy 680. Take the Alum Rock East Exit. Drive about 2.4 miles. Turn right on Mt Herman Rd./CA-130. There will be signs posted. Please follow them. Take Mt. Herman Rd./CA-130 about 8 miles. The Park entrance will be on your right. See park brochure for detailed map.
It cannot be stressed STRONGLY ENOUGH that the populace avoid Quimby Rd. with large vehicles or vehicles towing trailers.
