To get there from Auburn take Hwy 49 north to Nevada City where it turns left toward Downieville. Continue on toward North San Juan. Just short of town take a right on Tyler Foote Road. The road name changes to Cruzon Grade. Turn right onto Derbec Road. About 1.5-miles down the hill you arrive in historic North Bloomfield.
The Google map takes you on a back road. I'd stop in Nevada City and ask for directions
