Hellroaring Plateau (FS 2004)
Hellroaring Road to the Trailhead
Hellroaring Road (FS 2004) from Main Fork Rock Creek Road (FS 2421) to the trailhead at the end of the road: 5.6 miles one way (FS; the 2023 MVUM copy gives 5.64), about 11.2–11.4 miles round trip, returning the same way. The approach road number is FS 2421; the "NFSR #2241" in AGF's earlier listing is a typo carried from an Aug. 4, 2025 Forest Service release (no NFSR 2241 exists in the FS MVUM data).
Moderate · Narrow, Exposed Rocky Shelf Road
NO RECORD OF AGF DRIVING THIS ROUTE: the 4/10 is AGF's estimate, not an AGF run. AGF rates a trail by its hardest unavoidable obstacle in normal dry conditions. Here that is the narrow upper road with large drop-offs: an onX report (secondary, Aug. 31, 2025) says, "Not very technical but it is very narrow with thousand feet plus steep drop offs on the downhill side." onX (secondary) also says, "This is a very bumpy route with continuous rocky terrain and many sharp rocks along the way," and rates it 4. The Forest Service says "the Hellroaring Road is rocky with potholes. High clearance vehicles are advised." No locker- or winch-level obstacle is documented. Snow, ice, mud and fire are condition changes, not part of the base rating.
Snow, mud, runoff, deadfall and fire are condition changes, not part of the base rating.
Getting There
Forest Service directions: from the Beartooth Ranger District office (6811 Hwy 212, just south of Red Lodge), "Drive south on US Hwy 212 for 10.9 miles." "Turn right onto the Main Fork Rock Creek Rd (Forest Road 2421)." "Drive 0.9 miles past three campgrounds and bear to the right onto the Hellroaring Rd." "Drive 5.6 miles to the trailhead at the end of the road." Return the same way. Motor vehicles stop at the trailhead.
The pin is AGF's trail-record point for the trailhead; it falls within about 10 m of the end of FS 2004 in Forest Service MVUM data (not field-checked). No downloadable track is published: AGF's GPS archive has no track within 2 km of this route.

Last reviewed Oct. 12, 2026. No closure is listed, but FS 2004 is highway-legal only, the upper road is narrow with large drop-offs, snow and ice are likely from October, and the MVUM class should be checked on the 2026 MVUM. There is no record of AGF driving Hellroaring Plateau; the 4/10 is an estimate from official and secondary sources.
AGF ratings describe normal, dry-condition difficulty. They do not mean a route is legal, open or passable today. Spot something out of date? Use the Contact page.
