The Flagg Mountain Trail (Gorilla Trail) ends up in the camp a few minutes past the white farmhouse/office.
The Ball Mountain Trail (Banana Trail) trailhead isn't marked, but is acorss the street from a white house, a few dozen vertical feet up from bottom of the road. There's room to park at the end of the flats, just a bit down the road from the trailhead, on the same side of the road, near a logging operation.
