* What: ZipStream Aerial Adventure, a challenge course
* Being done by: Ruby Falls and The Adventure Guild, which specializes in adventure-based recreation outdoors.
* Location: Side of Lookout Mountain, adjacent to Ruby Falls
* Why the new addition? ZipStream is an effort to offer a different outdoor experience for tourists and residents, officials said. “We were looking for something to add to the attraction of natural quality and use the natural typography so everything looked the same,” said Hugh Morrow, president of Ruby Falls, longtime tourist site that has tours of caverns inside Lookout Mountain.
* Cost: $30 for admission
