About this trail
Mccarthy (USFS trail 4316) runs 1 mi through Caribou-Targhee National Forest in Idaho. The figures here are pulled from the official US Forest Service trail data for Caribou-Targhee 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. 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. 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 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, and the record carries an accessibility designation for this trail. Because conditions, closures, and local orders change between data refreshes, confirm the current status with the managing ranger district before you ride.
