Zim Zim Falls

Zim Zim Falls is a waterfall within the Knoxville Wildlife Area that drops roughly 100 feet in a single flow through a rocky canyon. The water feeds into Zim Zim Creek, a small stream that threads through the surrounding landscape of Berryessa-Snow Mountain National Monument.

The lands containing this waterfall became open to the public in 2005 when the Knoxville Wildlife Area expanded significantly. This expansion granted visitors access to previously restricted areas of the surrounding wilderness.

Local visitors come to this spot to experience the sound and sight of water falling through the canyon. The falls serve as a gathering point for those seeking a quiet moment in nature away from populated areas.

Reaching this waterfall requires at least two hours of hiking over terrain that changes in elevation and ground conditions throughout. Sturdy footwear and a water bottle are essential, as shaded rest spots are few along the trail.

The water from this falls travels through Zim Zim Creek and then into Eticuera Creek before reaching Lake Berryessa miles away. Few visitors realize they are witnessing the beginning of a journey that connects this remote spot to a major lake.
