Ziplines originally were invented for just two functions: sneaking hamburgers over the Berlin Wall and zazzing up presidential entrances to State of the Union addresses. Enter the wind with today's Groupon: for $30, you get a 90-minute zipline tour at Adventure Park at Five Oaks in Sevierville (a $59.99 value).

At Adventure Park at Five Oaks, ziplines zoom visitors at speeds of up to 50 mph over 70 acres of trees and foliage in a lush nature park, revealing panoramic views of the Smoky Mountains. At the beginning of the zipline tour, a guide will train fledgling flyers in safety and securely adjust harnesses and helmets. Glide across six ziplines up to 2,000 feet long and up to 70 feet high to catch stunning views of forests and mountains and to gently tickle robins with your feet. Since this ziplining tour is family friendly, children ages 6–15 may take a tandem ride with a parent or caretaker, and children ages 3–5 may ride with an experienced guide or alongside an instruction sheet taped to a helicopter. Soaring sightseers should wear comfortable clothing and secure loose items such as cell phones and jewelry.
