Deep in the backcountry of Idaho lies a protected wilderness area known as the Frank Church-River of No Return Wilderness. It encompasses a total of 2,366,757 acres, and it is the largest contiguous wilderness in the lower 48 states. The stunning region is characterized by rugged mountains, deep canyons and roaring rivers. The only direct way to access this area is a flight through steep canyons on a bush plane or a jet-boat journey through Class 5 whitewater rapids on the Salmon River. The wilderness area is home to a small community of homesteaders who are dependent on the pilots, boat captains and each other to survive. Discovery Channel's "River of No Return" introduces viewers to these homesteaders who rely on themselves, their neighbors and their survival skills to live life on their own terms in one of America's last frontiers.
