To make the body produce adrenaline, people usually must kick a cop in the chin, juggle soldering irons, or trap wild animals underneath wet newspaper. Today's Groupon gives you a more comfortable way to excite your cellular infrastructure: for $37, you get a Treetop Canopy Tour at Zip Line USA (up to $75 value), located in Reeds Spring near Branson. Customers must be three or older to take the zip-line tour.

Zip Line USA gives ground-based adventure-seekers the thrilling experience of traveling along the treetops of the Ozark Mountains. During the 90-minute Treetop Canopy Tour ($75 for adults, $65 for senior citizens), guests will walk along suspended platforms and bridges built up to 65 feet (or approximately 11 George Bretts) above ground. The Treetop Canopy Tour uses nine zip-line cables to let you soar through the foliage, taking in spectacular flying-squirrel's-eye views of the landscape and making acquaintances with the canopy's cordial avian life.

Guests will be fitted with all necessary safety equipment, and then given a quick lesson on a short zip line. Zip Line USA's course has been designed by industry-leading zip-line experts, and all cables and bridges are meticulously inspected to make sure your ride is safe and secure. Glide past glorious greenery, fascinating wildlife, and Antarctic penguins’ holiday tree resort with today's Groupon to Zip Line USA.
