I went to Branson Zipline and Canopy Tours (between Springfield and Branson). It was a lot of fun, the guides were super-friendly and you are ALWAYS hooked to a line (you have two ropes tied to your harness, they are big on safety, which is comforting)
However, it's definitely a "been there, done that" experience. I went on the "2.5 hour Ozarks Xplorer Canopy Tour" it was great fun, but at $99 for 2 1/2 hours...very steep, SDC
season passes are $77 by comparison. That said...it is a "been there, done that" experience that I would recommend to just about anyone
