Mossbrae Falls is one of the more scenic waterfalls in California. Approximately 50 ft (15.2 m) in height and150 ft (45.7 m) wide, the falls are fed by springs, which course down the canyon wall, and into the Sacramento River, creating the effect of many waterfall streams falling into the river. The entire course of the falls is longer than 50 ft (15.2 m), however the upper cascades cannot be observed through flora which covers the mountainside. The bottom 50 ft (15.2 m) is a straight plunge into the river.

The trail to the falls follows beside the Union Pacific railroad tracks, and is narrow in some places. The waterfall is to the right, immediately before a nearby railroad bridge.
