This trail is very steep in places with many switchbacks, as it winds its way down to the Middle Fork of the American River. About halfway down across the canyon, there is a pretty cascade of water coming down the canyon wall. The river has good fishing at times, and there are adequate campsites on the large gravel bars along the river. Fire permits are required for campfires, backpacking stoves, BBQs and lanterns. Because this is a southerly exposure, the trail can be hot during a warm day, and is a pleasant hike during the spring and fall. Poison Oak is present, especially at the beginning of the trail.
