Welcome to Prospect & Union Creek
A mile south of Prospect on Mill Creek Dr is the 0.3-mile trail to the awesome Mill Creek Falls (173ft). A side shoot leads to the Avenue of Giant Boulders, well worth the extra few steps, where the Rogue River crashes through rocky boulders (scrambling required).
A good 4.6-mile hike (one way) starts from either the Woodruff Bridge picnic area or the River Bridge campground; you'll get views of the pretty Takelma Gorge. You can also hike 3.5 miles (one way) between Natural Bridge, where the Rogue River borrows a lava tube and goes underground for 200ft, and the magical Rogue River Gorge, where a narrow, turbulent section of river cuts a sheer-walled cleft into a lava flow.
