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.

The record additionally permits Class 1, Class 2, Class 3 e-bike use; recall that Class 1 is pedal-assist, while Class 2 adds a throttle and Class 3 a higher cutoff 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, 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.
