Whitewater Adventures
River Rafting
Montana's Wild Rivers
Montana's rivers are the arteries of the landscape, carrying snowmelt from towering peaks through narrow canyons, across broad valleys, and into wild gorges that provide some of the finest whitewater experiences in the American West. Whether you're looking for a peaceful scenic float through Paradise Valley or an adrenaline-pumping Class IV ride through the Alberton Gorge, Montana's rivers deliver.
The rafting season typically runs from late May through September, with peak whitewater occurring during the spring runoff in June and early July. As water levels drop in late summer, the rivers mellow into perfect conditions for family floats, scenic trips, and combination fishing-float excursions.

What to Expect
Half-day trips typically last 3–4 hours on the water, while full-day adventures include 5–6 hours of rafting plus a riverside lunch. Most outfitters provide wetsuits, splash jackets, helmets, and life vests. Bring sunscreen, water shoes, and a change of dry clothes. Water temperatures range from the low 40s to mid-50s°F during peak season, so the provided wetsuit gear is essential for comfort. Expect to get wet, that's half the fun.
