This was my second time ziplining and Wahoo does it up right. Staff is friendly, personable and very helpful. My first zipline experience was in Hondoras during a cruise and while that experience was mindblowing, this Gatlinburg experience was definitely over the top! Pun intended! First-timers need not be intimidated by the first leap of faith here. My wife and I brought some friends with us (both 60yrs old) and we thought for sure our friend's wife was going to back out at the top of the first platform. The guide offered to tandem zip with her and she absolutely LOVED the experience. This is a MUST DO if you haven't experienced it! I'm deathly afraid of heights but the thrill of ziplining far overshadows that!!!
