Moon Falls is a fan-shaped waterfall on Alex Creek in the Umpqua National Forest, conventionally cited at about 100 feet though the Northwest Waterfall Survey measures it taller. Its short trail through old-growth forest pairs naturally with nearby Spirit and Pinard Falls.

Its 100 ft drop is taller than about 74% of the 775 waterfalls we track.

The falls are fed by Alex Creek. It lies in Lane, Oregon. The site is on public land managed by US Forest Service (Umpqua National Forest).

This is a short hike waterfall: reached by a short trail, generally under about a mile each way. The walk in is brief — comfortable shoes are usually all you need. The walk to the main viewpoint runs about 1 miles round trip. The nearest town is Cottage Grove.

When to go: Spring. Water volume swings with the seasons here, strongest after snowmelt or rain and lowest in late summer, so check recent streamflow before you go.
