Elk Mtn opened its doors in 2012 with the intent to bring a more personalized experience to the whitewater rafting & fly fishing industry. The owners, Lange, James & Conor, grew up together in Aspen exploring and working on the rivers of Colorado. Still their favorite place to raft & play was the Roaring Fork River, flowing through the heart of Aspen, their home. It was a natural progression for them to take their passion for this free-flowing river and find a way to share it the world!
