Whitewater Rafting Glacier National Park: Class II-III Rapids
Learn to paddle on flat water, then run rapids that demand everything you practiced
Half-day whitewater rafting near West Glacier takes you four miles of calm water first, where a live guide teaches paddle commands and team technique, then into John Stevens Canyon's Class II-III rapids. The raft, life jacket and paddles are included. Children from age 5 can join. Trips run rain or shine, and no experience is necessary: the early miles exist so you can execute the harder commands when the river picks up.

The experience
New to whitewater rafting? The first four miles are built for that. You'll learn paddle commands and how to move as a crew on relatively calm water, which means when the river picks up speed in John Stevens Canyon, you're not learning and running rapids at the same time. The guide is with you the whole way, calling out commands and reading the current. By the time you hit rapids named Bonecrusher, Jaws and the Notch, you've already practiced what they demand.
The trip runs 2.5 hours total and departs rain or shine. Class II-III rapids mean fast water and splashing, not a beginner's pool. You'll need the paddle work you learned upstream to stay coordinated through the bigger drops. The southern boundary of Glacier National Park runs alongside the route, so the terrain shifts from forested banks to the dramatic canyon walls as the water gets faster. Trip times can shorten when river levels run high early in the season, which is also when minimum ages are higher.
You need to be able to buckle a 58-inch chest life jacket and weigh at least 50 pounds. There's no maximum weight limit. Children from age 5 can join, though early-season trips may require older kids because of higher water. The raft, PFD and paddles come with you. Bring a change of clothes and secure anything that shouldn't get wet.

Is this one for you?Small groups work best here because the paddle commands need everyone moving together. You're learning as a crew in the flat section, then executing those commands through the rapids. If you have a free afternoon and want to try whitewater rafting without committing to a full day or needing prior experience, the half-day format and beginner-friendly early miles make this the right fit.
Traveler reviews
Top questions
Is this whitewater rafting trip safe for someone who has never paddled before?
Yes. The half-day trip starts with four miles of calm water where the guide teaches paddle commands and team technique before you reach the Class II-III rapids in John Stevens Canyon. That practice time is the whole point of the early section. It's built so you can handle the faster water when you get there.
What are the rapids like in John Stevens Canyon?
John Stevens Canyon holds Class II-III rapids with names like Bonecrusher, Jaws and the Notch. They're fast and splashy, and they demand the paddle work you learned in the first four miles. The canyon walls are dramatic, and the water moves noticeably faster than the upstream section.
Can my five-year-old join this trip?
Children from age 5 can join, and they need to weigh at least 50 pounds and be able to buckle a 58-inch chest life jacket. Early in the season when river levels are higher, minimum ages are raised, so check the current requirements before booking if you're planning an early-season trip.
What's included in the half-day rafting trip?
The raft, life jacket (PFD) and paddles are all included. The live guide is with you the whole 2.5 hours, calling commands and reading the water. Bring a change of clothes and keep anything that shouldn't get wet in a dry bag.
How long does the trip take?
The half-day trip runs 2.5 hours total. That includes the four miles of calm water where you learn, plus the rapids in John Stevens Canyon. Trip times can be shorter when river levels are higher early in the season.
What should I know about the water conditions?
Trips depart rain or shine, so weather doesn't stop the trip. River levels vary by season and affect both the trip length and the minimum age requirement: higher water means shorter trips and higher age minimums early in the season.
