WINTER CLOSURE TO WHEELED VEHICLES IS COMING, AND SOURCES DISAGREE ON THE DATES. BLM: "Winter access from either direction is only by snowmobile, snow shoes, or cross-country skis." The wheeled-closure dates conflict: Recreation.gov says roads are closed to wheeled vehicles "from January to May"; Visit Montana (state tourism, secondary) says Jan. 1–March 31; the Garnet Preservation Association (nonprofit co-manager) allows wheeled vehicles May 1–Dec. 15, depending on snow; the National Conservation Lands Foundation (nonprofit) says Jan. 1–April 30; and FHWA says wheeled access runs about May–December. Snow can stop wheeled travel before any of these dates. Call the BLM Missoula Field Office (406-329-3914) for the current dates. Use the Highway 200 side. The Bear Gulch approach from I-90 "should only be attempted by high-clearance vehicles with 4-wheel drive" (Recreation.gov); BLM calls it "steep, narrow and rough," "not recommended for trailers or RVs," and a one-lane road with no turnouts. RVs, travel trailers, low-clearance and oversized vehicles should use only the Garnet Range Road off Highway 200 (Recreation.gov). This guide's rating covers the Highway 200 side only. The visitor center is open late May through September (BLM), so it is likely closed now: expect no staff or services, and verify whether buildings are open. The $10 townsite fee applies; the byway itself has no fee (BLM). Leave all artifacts in place. The National Conservation Lands Foundation (nonprofit) says it is illegal to remove historic artifacts older than 50 years from public lands, and Southwest Montana tourism (secondary) lists no artifact removal, metal detecting or digging; AGF has not found BLM's own wording. One Garnet building is privately owned and there are mining claims in the area (Southwest Montana tourism, secondary; not confirmed by BLM): do not trespass. Read Know Before You Go.
AGF HAS NOT RUN THIS ROUTE. This guide is built from official sources (BLM, Recreation.gov and FHWA) plus clearly labeled secondary sources. No AGF field visit is behind it, and the 2/10 rating comes from those sources, not from an AGF drive.
WHAT THIS GUIDE COVERS

Highway 200 to Garnet Ghost Town

The 12-mile BLM Garnet Back Country Byway on the Garnet Range Road, from Highway 200 south to Garnet Ghost Town, climbing about 2,000 feet (BLM). FHWA describes the road as 3.7 miles paved and 6.4 miles gravel, plus short connectors. BLM says the Highway 200 entrance is a two-lane road that "can be rough in spots."

NOT INCLUDED: the Bear Gulch approach from I-90 (high-clearance 4WD only; excluded from the rating), winter over-snow trails, private property and mining claims, and the inside of historic buildings.
WHY 2/10

Easy · Rough in Spots

AGF rates a trail by its hardest unavoidable obstacle in normal dry conditions. The Highway 200-side byway is a two-lane road that can be rough in spots (BLM), with no documented technical obstacle. "All access roads can be rough and are minimally maintained" (Recreation.gov). The steeper, narrow, one-lane Bear Gulch approach is a separate route and is not part of this rating. Snow ends wheeled access in winter.

ROUTE & MAP

Getting There

Preferred (BLM): from Missoula, drive about 30 miles east on MT-200 and turn south between mile markers 22 and 23 onto the Garnet Range Road. Follow signs about 10 miles to Garnet (BLM; the byway itself is listed as 12 miles). The main parking lot is at the top of a hill just outside town, with two accessible spaces in town (BLM, 2025). Alternate, high-clearance 4WD only (Recreation.gov): from I-90, take the Drummond or Bearmouth exit, follow old US-10 to Bear Gulch Road, and follow signs up Bear Gulch for 11 miles to Garnet (BLM). Not for trailers or RVs.

Last reviewed Oct. 8, 2026. No closure was found, but the visitor center season has ended and the winter wheeled closure dates conflict across sources. AGF has not run this route.
