About Fern Falls
Fern Falls is a quiet, photogenic cascade tucked into the Boise National Forest and managed by the U.S. Forest Service. The falls sit amid dense forest and offer a peaceful reward for a moderate hike; many visitors describe the setting as lush and restorative, ideal for a half-day outing. The most direct approach follows a portion of the USFS South Fork Payette River Trail (Trail #7452), which leads you through classic inland Pacific Northwest woods and riparian scenery to the falls. The hike to Fern Falls is an out-and-back route of about 4.0 miles with roughly 500 feet of elevation gain and is generally rated moderate. The South Fork Payette River Trail is listed by the Forest Service at 16.62 GIS miles in total, so the falls are accessed via a maintained segment of that longer trail. Note that the nearest developed camping is at Yellowbelly Lake, about 17.5 km away, so plan overnight stays accordingly.
