Map Notes: The trail to Red Rock Falls (the red line) skirts along the banks of Lewis Creek for most of its route, though it climbs a hundred feet or so above it for the last stretch. The much shorter route to Corlieu Falls (the yellow line) starts well above the river and includes a steep descent to the viewing platform.
Though the trails feel isolated, they're never far from Highway 41, and you may hear traffic at various points along the way.
The trail continues north past Red Rock Falls to Sugar Pine, a private housing development. Maybe my timing was bad and I was there after a series of robberies, carjackings, and alien abductions, but the one time I hiked all the way to Sugar Pine and wandered through it, I got more "you'd better keep walking, stranger" stares from the locals than I have in all the rest of my life put together.
