About this trail
Rocky Pitch Loop (USFS trail 2664) runs 3.8 mi through Grand Mesa, Uncompahgre and Gunnison National Forests in Colorado. The figures here are pulled from the official US Forest Service trail data for Grand Mesa, Uncompahgre and Gunnison 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 Advanced (grade band 12-20%) — a steep steepness profile derived from USFS slope data, not a technical mountain-bike rating. Mountain bikes are allowed, with a Jun–Oct season in the data. On the electric side, Class 1, Class 2, Class 3 e-bikes are also designated (Jun–Oct) — 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 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. 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.
