You should have a high level of fitness and be comfortable with sustained paddling and exertion at altitude.
Ride the Numbers on the Arkansas River for a full day of continuous Class III–IV rapids through Browns Canyon. Expect steep drops, expert guides, and local scenes that explain why Buena Vista is a rafting hub.
The raft drops into a throat of granite and water, and for a dozen breathless seconds the Arkansas River takes charge: it shoves, buckles, and then spits you free into a spray of white. On the Full Day Numbers Rafting Adventure, the river isn’t polite—it's insistent. You’ll launch near Buena Vista and spend a day threading through tight canyon walls, steep drops and relentless rapids that earned this stretch a reputation as Colorado’s headline act for experienced paddlers.

Plan to arrive 45 minutes before departure to sign waivers, get fitted for gear, and hear the safety briefing.
Choose footwear with a heel strap to avoid losing shoes in fast water and protect feet on rocky put-ins.
Use high-SPF sunscreen, a brimmed hat under your helmet, and polarized sunglasses with a retainer.
