Horsepasture river has a series of fairly impressive waterfalls, with Rainbow Falls being the highest at 150 feet. Nearby Whitewater Falls, fed by a different river, is the highest the east, at 811 feet for both Upper and Lower Whitewater Falls, falling from North Carolina into South Carolina.
Several people per year are killed on waterfalls in Transylvania County, NC. There are hundreds of falls in that county. The moss that grows on the rocks is quite slippery. Stay off the rocks if they’re even damp is the best advice I can give.
