About This Trail

Imported description

A challenging loop for hikers is what it sounds like. In some places, there are no trail markers. There are some bushwhacking and high grass involved. It is possible to get to the Falls via the creek in the wet season. Many Nevada Creek crossings can be found back on the loop. It was said that you may hike at your own risk. There is a location on remote Berryessa Kelley Rd., which is about 6 miles north of the lake's north end. The parking is next to the concrete creek overflow section of the road. The hike begins at a gate outside of the parking area.
