Mill Creek Falls

Mill Creek Falls is a double waterfall within Prospect State Scenic Viewpoint that shares a carved rock face with Barr Creek Falls. Both cascades plunge into the Rogue River Canyon through a dramatic slot in the stone.

The rock formations around the falls contain layers of petrified volcanic ash from Mount Mazama's eruption thousands of years ago. This ancient geological event shaped the canyon and the cliff formations visitors see today.

The Mill Creek Falls Scenic Area incorporates viewing platforms and trail systems developed by Boise Cascade Corporation to enhance public access to natural landmarks.

A short trail of roughly half a mile departs from the parking area on Mill Creek Drive to reach observation platforms overlooking the falls. Multiple viewpoints along the route allow visitors to see both cascades from different angles.

The water flows year-round at a constant rate, keeping the falls forceful even during dry months when other regional waterfalls diminish. This reliable flow comes from mountain springs and snowmelt higher up in the watershed.
