About this trail
Bald Mtn Spur Trail (USFS trail 300.B) is a 2.4 mi trail in Pike and San Isabel National Forests, Colorado. This profile summarizes what the official US Forest Service trail record says about riding it: how long the trail is, what it's built on, how steep the route grades out, and which forms of bike use the agency has designated. The trail surface is not specified in the USFS record. No grade band is recorded, so a steepness-based difficulty isn't available for this trail.

Its USFS Trail Class (the agency's 1-to-5 development rating) isn't recorded for this segment.

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.
