One of the top experiences in the eastern Tennessee region, the Gatlinburg SkyBridge is 680 feet long and hovers 150 feet over the ground with terrific views of the surrounding mountains. Opened in 2019, the SkyBridge is the longest pedestrian suspension bridge in North America and a must-see activity in the region. It costs $19.95 for adult admission, $14.95 for children and is free for children under 3.
