I just finished a stint at the CDF Dispatch Center in Humboldt County. In the two years I worked there, I only dispatched emergency units to 3 traffic collisions on the Shelter Cove Road. One involved an RV. The road is tight and the reference that covers the grades is accurate. It is actually 21 miles from Garberville to Shelter Cove. It only seems like 40. It does take about 45 minutes to one hour to make the trip. While the road is not for everyone, C-Bill is correct that once there, on a clear day, the Lost Coast is some of the most remote and beautiful sections of the Pacific Coast. If I am not mistaken, the 26 or so miles of undeveloped coast north of Shelter Cove is one of the longest sections on the West Coast. So go and enjoy the scenery
