On the Numbers section of the Arkansas River, rapids come at you in quick succession; they’re numbered because there are too many to name.

The raft buckles against the current and the river answers—rock-churned water pushing you through a narrow ribbon of Colorado sky. On the Numbers section of the Arkansas River, rapids come at you in quick succession; they’re numbered because there are too many to name. The canyon’s walls close, the air smells faintly of pine and cold water, and every stroke feels earned.
This stretch runs through Browns Canyon National Monument territory, carved during the uplift of the Rockies and scoured by ice and meltwater over millennia. The river here slices through hard rock, producing steep, technical waves and holes that demand competent maneuvering. Buena Vista and nearby mining-era settlements shaped the local rafting culture—outfitters that have read these currents for decades run trips that balance adrenaline with precise rivercraft.
Expect continuous class IV–V whitewater on a roughly three-hour run, with rapid sequences that test endurance and teamwork more than one-off drops. Guides provide helmets, PFDs, and briefing; experience and quick reactions make the difference.
Practical guidance: arrive 45 minutes before launch at River Runners Browns Canyon, dressed in quick-dry layers and water shoes. Hydrate at altitude and secure eyewear with a retainer; sunscreen and a small, sealed camera are worth the space. If you have back, heart, or pregnancy concerns, skip this run—rigorous paddling and impact are constant. Plan post-trip recovery time: the energy output and Colorado sun can fatigue even fit rafters. For experienced paddlers craving a concentrated dose of whitewater, the Numbers delivers sharp, sustained excitement against real mountain scale.
The Numbers is an advanced run with continuous class IV–V rapids; it’s intended for experienced paddlers or guided trips for strong, physically fit participants.
Wear quick-dry layers, closed-toe water shoes, a sun hat with a strap, and bring a refillable water bottle; guides supply helmets and PFDs.
Outfitters typically restrict participation for young children and those with heart, back, or pregnancy concerns; confirm age and health policies when booking.
Late spring through summer offers sustained flows and warmer weather; spring brings higher, colder water for a more intense ride.
