Turtleback Falls, also called Umbrella Falls and Bust-Your-Butt Falls is on the Horsepasture River. It is about 20ft high. Although this is fun, people have died here over the years. Another point is just below this waterfall lies 150ft Rainbow Falls. People die there too! Go upriver a short walk and see Drift Falls. Access through Gorges State Park. One of our favorite places.
