From the dirt lot near Drydens Road, a short path reaches the Redwood Creek levee. Follow the levee toward the Rodeo Grounds, with pasture and wooded hills on one side and the creek on the other. Beyond the woods, a broad, horse-used trail climbs through mossy alders into redwoods, then opens into fern-covered groves with tall, straight trunks.
About 1.7 miles in, take the right-hand branch at the unsigned split. This less-used section leaves the redwood stand for mixed woodland, with much of the neighboring old growth screened by brush. Older markers may call this the Six Hour Loop. Later the route descends to a dirt-road junction, crosses a small channel of McArthur Creek by culvert, and climbs again; stay with the McArthur circuit rather than following the separate Ridge or Elam Creek loops.
