With the weather as hot as it is we have got to get cooled off and white water rafting is an excelent way to do it! Golly, there are so many places to raft in and around the Appalachian Mountains its hard to choose just one. Near Pigeon Forge/Gatlinburg, TN there is several rafting businesses right off the highway! From Asheville, take I-40 West all the way to Exit 447 and your there! Or, from Knoxville, TN area, take I-40 East to Exit 447. Either way is about 1 hour travel time.
There are several different rafting businesses in about a mile stretch... USA Raft, Rapid Expeditions, Rafting in the Smokies, & Big Creek Expeditions. Call around for the best price. I just recently picked up a brochure for $30/person at the Pigeon River Canopy Tours store (another adventure option!).
You will have a choice of rafting the Upper Pigeon River with it's fast pace rapids or the Lower Pigeon river that is known for being the more relaxing of the two.
You might want to bring a change of clothes but other than that, there is food you can buy there and they provide all of your gear. Once you call and schedule your trip, it can't get more stress free than that. So go ahead, have yourself a stress-free getaway!
