The Bob Marshall, Great Bear, and Scapegoat wildernesses run together across roughly 1.6 million acres, managed under shared direction by three national forests and five ranger districts. The Forest Service calls it the third largest wilderness complex in the lower 48. About 1,700 miles of trail, and no roads at all. The Chinese Wall carries the Continental Divide along its crest and stands roughly a thousand feet above the meadows at its base, and by most route accounts sits some 18 to 21 trail miles from the nearest common trailhead. Big Prairie, the ranger station in the middle of it, is a two-day walk from the nearest road and still gets its supplies by pack string. There is no scenic drive here, no shuttle, and no cell service.
If you are experienced
Plan a real trip.
No permit, quota, or fee is required to walk in, which surprises people. Nothing else about it is casual. Parties are capped at 15, food storage is legally mandatory, bridges are rare enough that fords are routine, and the high passes usually hold snow into early July. The classic Chinese Wall loop out of Benchmark runs about 60 miles and takes five to eight days.
If you want a guide
Go with an outfitter.
Outfitters have packed this country since about 1919 and they get people deeper in than most parties manage alone. Montana licenses the outfitter and the Forest Service permits the operation on a specific district, so confirm both, and treat a permit as authorization rather than a quality rating.
If you are curious, not committed
Look in from the edge.
This is a legitimate choice and more often than not the right one. Drive the reservoir to Spotted Bear, walk in from Meadow Creek for an afternoon, and turn around. You will see the country without turning your holiday into a rescue.
NavigationMap, compass, and the ability to use both when the trail is buried. Crews still clear those 1,700 miles with crosscut saws and axes, so an early season route on the map may not exist on the ground.
Food storageNot advice, a regulation. A Northern Region order requires bear-resistant storage across this country: a certified bear-resistant container, or a hang at least 10 feet up measured from the bottom of the load and 4 feet out from the support.
WeatherHigh passes are usually snow free around the Fourth of July, and usually is doing a great deal of work in that sentence. Expect weather in any month, and river crossings that rise with heat and rain.
Stock etiquetteHikers yield to stock. Speak up as soon as you see a string so the animals hear a human voice, step off on the downhill side because a startled horse bolts uphill, keep talking until the last animal is past, and never leave a pack sitting in the trail.
RegulationsFifteen people maximum, 35 head of stock, single file on trail. No bicycles, no e-bikes, no drones, no chainsaws, and no caching supplies for later. Camping is closed year round on the ground directly beneath the Wall. These are enforceable federal prohibitions, not suggestions.
EmergenciesAssume you are the first responder. Carry a satellite messenger, leave an itinerary with somebody who will notice you are late, and understand that help measured in hours beside a road is measured in days out here.
