About this trail
Kelly Mtn 4wd (USFS trail 2337) is a 1.7 mi trail in Idaho Panhandle National Forests, Idaho. The figures here are pulled from the official US Forest Service trail data for Idaho Panhandle National Forests, covering the trail's mileage, tread, grade band, and the bike and e-bike uses the agency lists as designated. USFS records list its surface as native material. Its grade-based difficulty is Intermediate (grade band 10-12%) — a moderate steepness profile derived from USFS slope data, not a technical mountain-bike rating. Note that mountain-bike use here is discouraged in USFS records — confirm with the ranger district before riding. On the electric side, Class 1, Class 2, Class 3 e-bikes are also designated — Class 1 being pedal-assist only, Classes 2 and 3 adding a throttle and higher assisted speed. The route is mapped as USFS Trail Class 3 on the agency's 1-to-5 development scale, where 1 is the most primitive, minimally maintained tread and 5 is the most developed. For day-of certainty on closures or seasonal orders, check directly with the ranger district, since this reflects the USFS data as of the latest refresh.

How we read this data
Grade-based difficulty above is the USFS grade (route steepness), not a technical mountain-bike rating — a gentle-grade trail can still be rocky or technical, and vice versa. Bike and e-bike status come verbatim from the USFS managed-use fields for this trail; we never infer access we can't cite. See our methodology for how the dataset is built and what each field means.
