Rafting the Middle Fork: A Full-Day Whitewater Adventure in Glacier National Park
A single-day, family-friendly rafting route that mixes class II–III excitement with Glacier National Park scenery and a riverside lunch
You feel the river before you see it. At first it is a distant, metallic susurrus tucked under cedar and larch, then a line of white teeth flashing where the current hits rock. The guide checks our life jackets, jokes with the kids, and names the first rapid — Bonecrusher — like it is a notorious uncle. We shove off into water that has traveled from glacial heights, and immediately the Middle Fork Flathead asserts itself: playful, unpredictable, and utterly clean. Over the next five to six hours the river will alternately prod and lull us, deliver a buffet-style lunch on a stony beach, and thread us beneath the historic Old Belton Bridge. By the time the bus takes us back to West Glacier, the day will feel like a scale model of Glacier National Park — an intense, wet slice of its wild heart.
Trail Wisdom
Wear river shoes
Avoid flip-flops; closed-toe river shoes or sturdy sandals prevent foot injuries on rocky shorelines and make swim re-entry easier.
Layer for cold water
Even on warm days the river is glacially fed; bring a lightweight insulating layer and a waterproof wind shell.
Hydrate and snack
Bring a refillable water bottle and quick snacks for before and after lunch; riverside sun can drain energy fast.
Protect electronics
Use a small dry bag or waterproof case for your phone and camera, and consider a floating wrist strap.

Conservation Note
The Middle Fork Flathead runs through areas with Wild and Scenic protections and local conservation efforts; operators practice leave-no-trace and advocate for watershed stewardship.
The Old Belton Bridge and Belton Chalet tie the river corridor to early 20th-century railway tourism; the Great Northern Railway shaped West Glacier as a gateway.
