About this trail
In Colville National Forest, Washington, Sullivan Creek (USFS trail 565) covers 1.4 mi of National Forest System trail. The figures here are pulled from the official US Forest Service trail data for Colville National Forest, 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. USFS slope data puts it in the Easy band (grade band +5-8%), meaning a gentle climb — keep in mind this measures steepness, not trail technicality. Mountain bikes are allowed, open year-round in the data. No e-bike class (1, 2 or 3) is designated on this trail in the USFS data, so treat it as a non-motorized route unless a posted order says otherwise. The route is mapped as USFS Trail Class 4 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.
