River Description
This section of the Wild and Scenic Middle Fork of the Flathead River offers a long season, moderate whitewater, and very scenic surroundings. Paddlers can run it from spring through fall, but conditions vary with flow. Those seeking a more challenging experience may find May and June high flows ideal, while those preferring a less demanding run may wish to avoid the spring snowmelt. The river corridor is framed by Glacier National Park on river right and the Flathead National Forest on river left, providing scenic forested and mountain views, though it is not true wilderness, with a railroad running along much of the river-left bank. Outfitters offer raft trips out of West Glacier, and this reach is the most popular day trip on the Middle Fork Flathead.
Named rapids on this section, in order, are Tunnel, Bonecrusher, Washboard, Big Squeeze, Jaws, Pinball, Repeater, The Notch, and Pumphouse. Boaters can expect swirly eddies, fun surf waves, and good recovery pools between rapids at medium flows. The combination of continuous moderate whitewater and varied features gives this section a dynamic character suited to intermediate paddlers.
The put-in is at the well-signed Moccasin Creek access area along Highway 2. West Glacier offers a couple of take-out options: hand-carry craft can exit at the historic Belton Bridge via a short but steep trail, while the formal take-out used by rafts and outfitters lies downstream on river left, with a large parking area and facilities. Boaters seeking solitude and riverside camping will find other reaches of the Middle Fork more appealing, but for a great whitewater day trip, this is the most popular section.
As always, please clean, drain, and dry boats before launching on the Middle Fork to protect its outstanding water quality from aquatic invasive species.

...River Features
Moccasin Creek, Put In
This access is located on Moccasin Creek and is the most popular launch point on the river as it is the closest launch to the major whitewater. You will encounter a high volume of outfitters utilizing this site. You float down the creek a short distance before it joins the Middle Fork making it a good put-in option but not a practical option as a take-out for those floating down from upstream. It is just over 3 miles on the Middle Fork to the start of the signficant whitewater at Tunnel.
Tunnel Rapids
This first signficant rapid is named for the nearby railroad tunnel on river left. The current accelerates into a series of waves and small holes that set the tone for the run. It’s a good warm-up, with clear lines and fun wave action.
Bonecrusher
Bonecrusher begins where the river bends back around to the left. The rapid is formed by boulders and paddlers can expect a hole at the bottom. At higher flows the rapid feartures large waves and a few strong holes. The main current pushes hard into the center, but there are straightforward lines with attentive boat placement. At medium flows it’s big and fun, but it packs more punch at high water.
Washboard
Washboard is a long series of continuous wave trains. Expect bouncy, splashy fun with few technical moves required in this read and run rapid.
Big Squeeze
At Big Squeeze the river passes between bedrock outcrops that narrow the river creating pushy water and large diagonal waves. The feature demands precise boat control to stay clear of surging laterals. It is short but powerful, and gets especially challenging at higher flows.
Screaming Right
The current flows over a ledge down the left and then current accelerates to the right into a strong wave train and lateral features that live up to the name. The rapid is energetic and fast, with boaters needing to stay centered and ready to punch through waves. It’s one of the more exciting rides on the run.
Jaws
Jaws is a standout rapid, with large breaking waves and a dynamic main hole that can pack a bite. Lines vary with flow, but the rapid often provides strong surf potential. It’s thrilling yet manageable for intermediates who stay on line. At lower flows the rapid is not in and boaters will hardly notice the easy class II features where this rapid forms.
Pin Ball
True to its name, Pinball features scattered boulders and bedrock walls that create pushy currents. At most flows it’s playful but requires attentive maneuvering and at lower flows it is an easy class II.
Repeater Rapids
With a gravel bar on the left and a rock wall on the right, Repeater serves up a string of similar-sized waves and holes, coming one after another. The rapid delivers consistent action over its length.
CBT Rapids
Named for the “Coal Bank Turnout” along Highway 2, CBT offers a mix of waves and diagonals that feel bigger than they look from shore. The rapid can be surprisingly pushy, especially at medium to high flows. Quick reactions and maintaining momentum are key.
The Notch
This rapid funnels through a narrow slot, creating a strong constriction in the current. Depending on flows, the Notch can be pushy with powerful waves and turbulent eddies. It’s one of the more technical features of the run and a highlight of the section.
Pumphouse
The final named rapid, Pumphouse, offers a boisterous finish with big waves and swift current. It’s a straightforward but splashy ride before the river eases toward West Glacier. A fitting capstone to a run full of character. Many groups stop near this rapid to enjoy lunch during the warm summer months.
Belton Bridge
The Belton Bridge as the original access into Glacier National Park until the 1964 washed away much of the bridge just leaving the arch. Today the bridge is open to foot, bicycle, and horse traffic and is a popular day use site where people access the river for water play. It is possible to exit the river here for those with hand-carry craft but it is not a practical take-out for rafts or larger craft.
West Glacier, Take Out
This is the primary take-out access off River Bend Drive in West Glacier on river left. Private property adjoins this area so please respect the neighbors. The site see heavy use by outfitters with buses and large trailers of boats coming and going throughout the day.
Trip Reports
Log in to add a reportWe paddled this section of the Middle Fork Flathead on the final day of a five-day packrafting trip from Granite Creek to Blankenship Bridge, camping the previous night just upstream of the Moccasin Creek Access toward the end of the Nyack Flats. Although flows were low at 730 cfs, there was still plenty of water to enjoy the run, and we encountered several outfitted rafting trips filled with guests having a great time. At this level, the whitewater was mostly Class II and III; Jaws and Pinball were not in, and guides we spoke to noted that those features only emerge at higher flows.
From Moccasin Creek it was about an hour of floating before reaching the first significant rapid, Tunnel, and the total run took us roughly 2.5 hours on the water. We stopped for lunch at a pleasant gravel beach on river right just below Pumphouse.
The run was scenic, with exceptional water quality and Glacier National Park forming the river-right shoreline. While the railroad hugs much of the river-left bank and its presence was noticeable, it did not overly detract from the experience.
From West Glacier we continued downstream onto the next run toward Blankenship Bridge.
Class II-III rapids at higher flows. class 2 at low flows. Jaws and Pinball are far from a 'class IV' rapid.
