Whitewater Rafting the Gallatin River

The Gallatin River offers some of the most exciting whitewater in southwest Montana, with rapids ranging from mellow Class I riffles to adrenaline-pumping Class III and IV stretches through the Gallatin Canyon. Local outfitters run guided half-day and full-day trips from late May through August, when snowmelt keeps the river running high and fast, providing all the gear, safety instruction, and expertise needed for a thrilling ride through this dramatic canyon.

Trips are available for a range of experience levels, including gentler float sections well suited to families with kids, so there's an option whether you're chasing big rapids or a scenic paddle. Many outfitters also offer combo packages pairing a morning on the river with an afternoon barbecue or fly fishing add-on. Book early in the season, as summer weekends fill up quickly with both locals and visitors eager to get out on the water.
