You push off from a rocky creek-side launch and the river instantly grabs attention — a narrow corridor of churning water framed by granite boulders and the raw angles of the Collegiate Peaks. The Numbers section doesn’t give you room to coast; rapid follows rapid, each one demanding steady strokes, quick braces, and the kind of team timing that turns chaos into flow.

You push off from a rocky creek-side launch and the river instantly grabs attention — a narrow corridor of churning water framed by granite boulders and the raw angles of the Collegiate Peaks. The Numbers section doesn’t give you room to coast; rapid follows rapid, each one demanding steady strokes, quick braces, and the kind of team timing that turns chaos into flow.
This six-mile run through central Colorado runs past geology shaped by glaciers and uplifted granite. The valley carries the imprint of 19th-century miners and early river guides who turned the Arkansas into a corridor for both industry and recreation. Local culture still orbits the river: guide outfits in Buena Vista, a community threaded with climbing and two-wheel culture, stage daily runs when flows allow.
Expect consistent Class IV rapids — features named by guides for their character, like the pinballing rapids where boulders change your line in a heartbeat. Guides provide helmets, PFDs, wetsuits, and instruction; guests should be ready for active paddling and brief shore time for safety talks. The run is three hours from outpost to return, including a shuttle and boat-to-shore transitions.
Practical advice: arrive 30 minutes early, complete waivers online, and layer for cold water and sun. Hydrate the day before and wear sturdy water shoes that won’t slip off. For anyone with solid paddling basics and a moderate level of fitness, the Numbers delivers relentless whitewater that rewards teamwork and leaves you with mountain views only a river can reveal.
