Wednesday, Sept 13, 2017 (California) Garberville (Benbow KOA) to Grizzly Creek Redwoods State Park We headed north into Humboldt Redwoods State Park, and drove the Avenue of the Giants, a 31-mile stretch of "old Highway 101." The stunning trees make this an awe-inspiring drive, but also nerve-wracking at times. We had read that there are often side mirrors from RVs lying at the side of the road, because the giant tree trunks are so close to the edge of the pavement and some drivers misjudge where their mirrors are, or simply can’t move out of the way because of oncoming cars.
