A half-day Class III rafting trip on the Arkansas River through Browns Canyon National Monument — this guide outlines the rapids, scenery, wildlife and the firm requirements to join Monumental Expeditions.
Class III Through a Forested Chasm: Half-Day Browns Canyon Run.
Browns Canyon National Monument is the Arkansas River’s most popular short run: a forested canyon of sculpted walls and boulders where splashy Class III rapids like Canyon Doors, the wave‑filled Zoom Flume and the seven-step Staircase punctuate long, clear pools. Expect trout-rich water, frequent sightings of Blue Heron and Bighorn Sheep, and a half‑day of whitewater that’s memorable for families and groups alike.
