About this trail
Flambeau Atv U.D (USFS trail 118J) is a 3.5 mi trail in Chequamegon-Nicolet National Forest, Wisconsin. This profile summarizes what the official US Forest Service trail record says about riding it: how long the trail is, what it's built on, how steep the route grades out, and which forms of bike use the agency has designated. The tread is mapped as imported compacted material. No grade band is recorded, so a steepness-based difficulty isn't available for this trail. Bike use is designated as allowed, typically Jan–Mar, May–Dec. On the electric side, Class 1, Class 2, Class 3 e-bikes are also designated (Jan–Mar, May–Dec) — 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.
