Mill Creek Falls Trail

Overview

This out-and-back clocks 3.8 miles total and earns its “moderately strenuous” tag. The payoff is Mill Creek Falls, a 75‑foot plunge where East Sulphur and Bumpass Creeks meet—the tallest waterfall in the park. The 2021 Dixie Fire opened swaths of forest along the route, which means wider views (and more sun) as you traverse the hillside and follow East Sulphur Creek.

Trail Experience

Start behind the amphitheater by the Southwest Area parking lot near the Kohm Yah‑mah‑nee Visitor Center. The path immediately rolls—expect a series of dips and rises that weave in and out of gullies, with creek crossings and sections that narrow or turn rocky. You’ll spot Brokeoff Mountain and Mount Diller along the way and, in season, open hillsides with mule ears (usually by July) plus blue and white stickseed. Deer and a variety of birds are commonly seen. Views to the falls and surrounding slopes are more open post‑fire, though some angles to the cascade remain partially tucked by terrain.

Difficulty and Terrain

While the distance is modest, the elevation change adds up: roughly 925 feet of loss outbound and the same gain on the way back (about 1,850 feet cumulative). Sturdy boots with good tread are smart, and trekking poles help on the steeper, rockier bits and the creek crossings. Parts of the route are narrow with loose, ashy dirt from the burn—expect dust on dry days.

Best Time to Hike

Portions of the trail are moderately sun‑exposed. Start early or late to avoid peak heat, and carry plenty of water. Wildflower interest typically ramps up by July on the open slopes.

Extensions

Beyond the falls, the trail continues across East Sulphur and Bumpass Creeks toward Crumbaugh Lake and on to Kings Creek Picnic Area. That extension includes a steep 750‑foot climb—great if you’re craving more cardio and broader scenery.

Safety Notes

You’ll pass through burn zones from the 2021 Dixie Fire. Be alert for snags (dead standing trees), shifting soils, and increased wind exposure. Factor the uphill return and the sun into your turnaround time.
