Overview
The Gallatin River is a tributary of the Missouri River, approximately 120 mi (193 km) long, in the U.S. states of Wyoming and Montana. It is one of three rivers, along with the Jefferson and Madison, that converge near Three Forks, Montana, to form the Missouri. It originates in the northwest corner of Yellowstone National Park in northwestern Wyoming, in the Gallatin Range of the Rocky Mountains.
Practical Info
Suggested Duration0.5-1 day
Best TimeLate May through June is thrilling for high-adrenaline whitewater rafting due to cascading spring snowmelts, while July through September stands as a world-class pilgrimage window for fly fishing. Hit the river banks between 6:30 AM and 9:30 AM on a clear summer morning; the water is cloaked in ethereal rising river mists as direct sun pierces the steep canyon walls, exposing trout swimming in the river beds.
Getting ThereThe river runs parallel directly alongside the scenic corridor of highway US-191 for dozens of miles. Self-drivers have unlimited access: navigate south from Bozeman down US-191 South, where dozens of clearly marked US Forest Service (USFS) pull-offs, fishing access sites, and suspension bridges line the highway shoulder with free parking. No transit buses run down this deep canyon highway corridor.
Travel Tips
- Private boaters floating US-191 rapids require a non-resident water recreation permit from Montana FWP and are subject to mandatory clean-drain-dry aquatic invasive species inspection.
- River banks feature steep, loose rock drop-offs, and wading beds are slick with river moss; anglers must wear heavy-duty studded wading boots to maintain stabilization.
- Water temps linger near 40-50°F year-round; accidental immersion risks hypothermia within minutes, banning open swimming without insulating neoprene wetsuits.
Reviews
Positive
- This clear, rushing river is a premier mecca for fly fishing and whitewater rafting; the filming location for 'A River Runs Through It' completely lives up to its name with stunning canyon views.
- There are plenty of well-planned public access points along the river, equipped with spacious pullout parking areas and clear signs, making it easy for anglers and kayakers to enter.
- This is a wonderful, free natural attraction with no river fees required; driving along the route or picnicking by the banks lets you enjoy high-value ecological scenery for free.
- Local rafting and guiding companies are managed professionally with excellent safety gear, and coaches are humorous and experienced, ensuring both safety and fun in the rapids.
Heads up
- Highway 191 running right alongside the river has heavy, fast-moving traffic; some parking spots are too close to the main road without safety barriers, requiring extra care with kids.
- The river water is mostly alpine snowmelt and remains bone-chilling cold even in peak summer; falling in or lacking professional waders/warm gear poses a hypothermia risk.
- Due to its fame, core fishing spots and popular rafting put-ins get highly crowded, occasionally leading to bumper-to-bumper anglers and ruining the sense of wilderness peace.
- Most public access points along the river offer only very primitive porta-potties, and trash cans are lacking, requiring visitors to strictly pack out all of their own garbage.
