Searching for that adrenaline filled trip of a lifetime? On Cross Mountain you better be prepared to grip and rip! Located on the lower Yampa, Cross Mountain Canyon is one of the most beautiful stretches of water in Colorado. Huge Class III and IV rapids will challenge the most experienced boater, while breathtaking canyons climbing 1,100 feet on both sides will dare you to get distracted by its beauty. Due to the seriousness of the whitewater, ages 16 and older please.
