About this trail
Boomerang Valley Floor (USFS trail 5435) runs 0.8 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. The tread is mapped as native material. Its grade-based difficulty is Easy (grade band 5-8%) — a gentle steepness profile derived from USFS slope data, not a technical mountain-bike rating. Bike use is designated as allowed year-round. The agency lists no Class 1, 2 or 3 e-bike designation here; absent a local order to the contrary, that means e-bikes are not an allowed use on this trail. 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. Treat this as a planning reference rather than a live conditions report, and verify any time-sensitive closure or order with the ranger district that manages Grand Mesa, Uncompahgre and Gunnison National Forests.
