Prospect State Scenic Viewpoint, State scenic viewpoint in Jackson County, Oregon, United States

Prospect State Scenic Viewpoint is a forested park in Jackson County that features two cascading waterfalls accessible via walking trails. The property includes geological rock formations and multiple viewing areas positioned at different elevations along the water courses.

The falls area was a private hiking site called Mill Creek Falls Scenic Area, developed by Willamette Industries along the Rogue River. A hydroelectric dam built in the 1920s drained the narrow valley holding the falls, exposing a group of large boulders now known as the Avenue of the Giant Boulders. A trailhead later developed by Boise Cascade leads to the falls.

Barr Creek Falls takes its name from a cattle bar once placed beside the waterfall to keep cattle from straying off neighbouring private ranches. The falls are also recorded as Bear Creek Falls. The trailhead for the falls was developed by Boise Cascade, and the paths fork toward the Avenue of Boulders on one side and the falls on the other.

The park is free to enter and offers maintained trails of varying difficulty suited to different fitness levels. Visiting during warmer months makes the trails drier and easier to walk, while water flow is most visible during spring.

The Avenue of the Giant Boulders appeared after a hydroelectric dam built in the 1920s drained the narrow valley holding the falls, exposing a group of large boulders that became a local attraction. The trailhead forks left toward the boulders and right toward Mill Creek Falls and Barr Creek Falls.
