About this trail
47832 (USFS trail 47832) is a 1.3 mi trail in Custer Gallatin National Forest, Montana. Everything below comes straight from the US Forest Service National Forest System Trails dataset — length, surface, slope-derived difficulty, and the specific bike and e-bike designations on record — so you can check legality before you load up. Underfoot, the trail is recorded as native material. Its grade-based difficulty is Intermediate (grade band +8-10%) — a moderate steepness profile derived from USFS slope data, not a technical mountain-bike rating. Bike use is designated as allowed year-round. The record additionally permits Class 1, Class 2, Class 3 e-bike use; recall that Class 1 is pedal-assist, while Class 2 adds a throttle and Class 3 a higher cutoff speed. The route is mapped as USFS Trail Class 2 on the agency's 1-to-5 development scale, where 1 is the most primitive, minimally maintained tread and 5 is the most developed. Because conditions, closures, and local orders change between data refreshes, confirm the current status with the managing ranger district before you ride.
