About this trail
Bald Mtn Spur 4wd Trail (USFS trail 16E29) is a 1.1 mi trail in Eldorado National Forest, California. Everything below comes straight from the US Forest Service National Forest System Trails dataset — length, surface, slope-derived difficulty, and the specific bike and e-bike designations on record — so you can check legality before you load up. Underfoot, the trail is recorded as native material. Based on slope, this is a Intermediate trail (grade band 10-12%); that reflects moderate gradient and is not the same as a technical MTB difficulty rating. For traditional mountain bikes, use is not designated according to USFS data. On the electric side, Class 1, Class 2, Class 3 e-bikes are also designated (Apr–Dec) — 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. 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 Eldorado National Forest.

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.
