The only zipline in the Smoky Mountains that zips over a waterfall, the Foxfire Mountain Waterfall Canopy Tour is a great way to see the beautiful Great Smoky Mountains. Travel over creeks, rock cliffs, valleys, mountains and back to base camp. There are seven different lines and two sky bridges with platforms. The initial training includes practicing on a 60-foot zipline, and guides remain with you during the entire adventure. All riders must be at least seven and weigh between 45 and 265 pounds.
