The expert guides of 5 Rivers Adventure make it easy to explore the natural beauty of the Smoky Mountains through rafting trips. The rafting adventures take groups down the dam-controlled Pigeon River's class I-IV rapids, which race past the Cherokee National Forest, Martha Sundquist State Forest, and the Appalachian Trail. Caving explorations, meanwhile, descend into the subterranean world beneath the Appalachian Mountains.
