About Sullivan Creek Falls

Sullivan Creek Falls is a quiet, forested cascade tucked into Oregon’s Willamette National Forest and managed by the U.S. Forest Service. The falls sit along Sullivan Creek and offer a peaceful retreat among firs and mixed conifers, making it a rewarding destination for hikers who prefer a less-crowded natural setting. The site’s woodland character and approachable scale make it a pleasant half-day outing for families and day hikers alike. The most direct route to the falls follows the U.S. Forest Service’s NASTY ROCK Trail (Trail #3356). This out-and-back route is moderate in difficulty and covers roughly 2.4 miles round trip (about 2.22 GIS miles) with approximately 350 feet of elevation gain. As part of the Willamette National Forest trail network, NASTY ROCK provides a natural-surface path through classic Cascade forest, making the waterfall a satisfying reward at the end of a short, steady climb.
