The Lower Whitewater Falls Trail starts just short of the North Carolina - South Carolina border on Hwy. 130 from a parking lot of Duke Power's Bad Creek Hydroelectric Station. This 2-mile hike in to an overlook for the falls is moderately strenuous, and provides a series of great views through extremely varied terrain.
About 20 miles north of Walhalla, SC is the Yellow Branch Recreation Area, which contains the trailhead for the Yellow Branch Falls trail. This trail winds its way across streams may times before reaching the Yellow Branch waterfall. This trail is about 1.5 miles to the falls, and it is an easy-to-moderate hike.
The East Fork Trail is part of the South Carolina Foothills Trail, an 80-mile trail stretching from Oconee State Park to Table Rock State Park. This section of the trail begins about 20 miles north of Walhalla and follows the East Fork of the Chattooga River. The trail itself is gorgeous, offering views of lush fields of ferns, rushing rapids, and amazing rock faces.
