2–3 hours
Moderate fitness; able to paddle intermittently and perform basic swim self‑rescue.
Launch from Noah’s Ark and run class II–III+ rapids through Browns Canyon National Monument. This tight half‑day on the Arkansas River balances pulse‑raising rapids with big canyon views and practical guide‑led instruction.
The raft drops into a corridor of granite walls and high desert sage; water that looked polite at the put‑in picks up a voice and starts to speak in splashes. Paddles slice, guides bark a cadence, and the Arkansas River - in this stretch through Browns Canyon National Monument - pushes the boat through a compact succession of class II–III+ rapids that demand attention but reward with speed and scenery.

Rocks and wet boat decks make sturdy, quick‑dry footwear essential — no flip‑flops.
A lightweight, quick‑dry base layer and a splash jacket keep you warm and protected from spray and sun.
Bring a refillable bottle to leave on shore; cold water and exertion on the river dehydrate quickly.
Practice paddle commands and self‑rescue instructions during orientation — follow them on every rapid.
Browns Canyon was designated a national monument in 2015; the Arkansas River corridor has long been shaped by mining, ranching, and recreation.
River health hinges on responsible tubing and leave‑no‑trace practices; operators follow guidelines to minimize shoreline impact and protect riparian habitat.
