4–5 hours
Moderate fitness: able to paddle intermittently, brace through rapids, and perform basic self-rescue if you swim.
Run 16 miles of the Arkansas River through Browns Canyon National Monument on a full-day rafting trip from Buena Vista. Expect 4–5 hours on the water, big rapids like Seidel's Suckhole and Twin Falls, riverside lunch, and professional guides.
The raft bucks, the guide barks a crisp command, and the Arkansas River takes over — cold, fast, and indifferent. You push forward into a bowl of stone where walls shrug upward and the current carves the day in a strip of whitewater. For the next 4–5 hours a 16-mile corridor of Browns Canyon National Monument does what rivers do best: it makes you move with it.

Plan to arrive at Noah's Ark at least 30 minutes before departure to check in, be fitted for a Type V life jacket and helmet, and review safety briefings.
Hydration matters — the sun and exertion add up; bring a secure reusable bottle inside a dry bag or use the guide's cooler.
Sturdy, secure footwear is required for swims and scrambling on rocky shorelines — sandals or flip-flops are not allowed.
You must be able to self-rescue in the event of a swim; if unsure, discuss concerns with the guide before launch.
Browns Canyon was designated a national monument in 2015, protecting a stretch of the Arkansas River and surrounding rocky terrain that supported mining and ranching communities in the 19th century.
Commercial permits and monument status limit development; practice Leave No Trace and avoid disturbing riverbanks to protect riparian habitat and nesting birds.
Secure grip and protection when footing on rocky shorelines and in the raft.
Lightweight moisture-wicking clothing and a wind/sun shell keep you warm and protected on long river hours.
Protect your electronics and essentials while still allowing easy access for photos.
Adds warmth and comfort during cold spring runoff when water temperatures are lowest.
