6–7 hours
Moderate fitness—comfortable with repeated paddling, getting in/out of boats, and spending hours on your feet.
Run the Arkansas through Brown's Canyon on a full-day guided trip from Buena Vista. Expect lively class III rapids, canyon walls of exposed rock, and a mix of thrills and natural history across a 6½-hour outing.
The raft drops into a throat of stone and river: walls tighten, water compresses, and the current seems to pick up a purpose of its own. Paddles bite in unison as the boat surges through a series of teeth—lively, smart rapids that laugh at timid hands and reward steady strokes. Above the noise, cliff faces peel back into pine and scrub; gullies cut deep into ancient rock. This is Brown's Canyon on the Arkansas River, and a full-day commercial run here is half geology lesson, half adrenaline fix.

Buena Vista sits near 7,900 ft—drink extra water the day before and bring a reusable bottle to refill at the meeting point.
Use a dry bag or wrist-tether for cameras and phones; river spray and rogue waves will find unprotected devices.
Closed-toe water shoes with straps protect feet during boat entry/exit and on rocky shore breaks.
Guides call commands for safety and to position the raft for the safest line—follow instructions promptly.
Brown's Canyon was designated a National Monument in 2015 to protect its rugged granite canyons carved by the Arkansas River; the area was historically used by Native peoples and later by miners and ranchers.
