Challenging
Nyack Creek is Glacier’s rough-and-tumble south-side trek: remote, brushy, and blissfully quiet. As described here, the Nyack Creek Trail runs up the valley from the park’s boundary after a mandatory ford of the Middle Fork Flathead River. The out-and-back distance is about 34.6 miles total with roughly 2,854 feet of gain, typically taking around 12 hours 50 minutes of moving time. Many backpackers link it into the larger Nyack–Coal Creek circuit (about 42–43 miles), but even the Nyack segment alone feels like true wilderness travel.
Expect a mix of dark timber, big burn scars with long, shadeless stretches, and a wild corridor that sees very little traffic. You’ll get intermittent peeks toward hulking south-side summits like Mount Stimson and occasional glimpses of the Middle Fork. Sections can be waist- to chest-high with brush, and blowdowns are common, so progress is slower than the stats suggest. In late summer, thimbleberries and huckleberries sweeten the deal. Water is plentiful from creeks along the way, and some parties rave about swimming holes and a waterfall near Lower Nyack when doing the broader route.
Getting there is the crux: you must ford the Middle Fork of the Flathead River at Nyack Crossing to even start. This crossing can be deep and fast depending on flows and may be impassable at times. Once committed, expect multiple unbridged creek fords (including Nyack and Harrison Creeks), heavy overgrowth, and stretches where the tread all but disappears. This is serious bear country with very low human traffic—treat it with the respect it deserves.
This is not a winter route. Late summer into early fall (September–October) typically brings lower, slower river levels that make the Nyack Crossing more feasible. Early August can work in lower-flow years, but conditions vary. In midsummer, burn areas can be hot and exposed, and brush is at its thickest. Always check current river and trail conditions with rangers before you go.
You’re traveling through the park’s ancient Belt Supergroup—layers that elsewhere in Glacier preserve early-life stromatolite fossils—while fire-shaped landscapes create long, open slopes. The mix of old forest, regenerating burns, and big creek valleys gives Nyack its wild, off-the-grid character.
Day hiking requires no permit. Overnight trips require a backcountry permit. Designated backcountry campgrounds on this route (e.g., Lower/Upper Nyack; and popular options along the broader loop) require reservations via the park’s backcountry system. In the Nyack–Coal Creek Camping Zone, dispersed camping is allowed but still requires a backcountry permit. Pets are not allowed on Glacier’s trails.
Choose Nyack if you crave solitude and can handle serious river fording, navigation challenges, and a primitive, slow-going tread. If you want easy trail and constant big vistas, there are better options elsewhere in the park. If you want deep wilderness vibes without the Nyack ford, consider routes that don’t require crossing the Middle Fork.
Roadside pullouts along US-2 near Nyack Crossing (between mile markers 164–165); from there you must ford the Middle Fork Flathead River to access the trail.
Initial river ford can be deep and swift; multiple unbridged creek fords; heavy brush and blowdowns obscure tread; serious grizzly habitat; significant sun exposure in burn areas; navigation is non-trivial—carry offline maps and a printed topo.
