A little was north is a fire road gate to the west side of the road. Up fire road through forest 3/4 mile to first fork stay left at, 1.5 mile there is hiking trail.( not legal ) Then at 4 miles a fork to south peak Stay right to the top of North peak where on a clear day it is possible to see Lassen, the coast, The City, Mount Shasta. The view is worth the pain and on the way back down stop at south peak then get the brakes hot for a 2000' run to the road. Nice Single Speed burn
Off of hwy 29 between Calistoga and Middletown There is parking for Robert louis Stevenson Memorial State Park.
