Browns Canyon National Monument, composes a thirteen-mile stretch of the Arkansas River beginning at Fisherman’s Bridge and ending at Stone Bridge. The section contains fourteen named Class II–III rapids such as Zoom Flume, Pinball, and Staircase. Daily trip options include a half-day and full day trip. The half day trip covers eight miles and the full day trips span the 13 mile canyon stopping for a riverside lunch midway. The browns canyon multi day option spans 2 days with 1 night camping in the river canyon.

The Numbers delivers Colorado’s most consistent and technical Class IV whitewater. The six-mile main section drops roughly seventy feet per mile from the Numbers Put-In to Railroad Bridge, featuring 6 big drop class IV rapids. For full-day trips, the adventure continues downstream through The Narrows, adding another 7 miles of Class II–III whitewater for a change of pace and stunning scenery after lunch. Half-day trips focus entirely on the core rapids for those who want maximum action in a short time. Multi day expeditions begin here as well, combining The Numbers with Browns Canyon, the Royal Gorge, and/or Bighorn Sheep Canyon for 2 or 3 day options.
