Trail facts

Length: 0.3 mi mapped
SAC hiking scale: Demanding mountain hiking (T3)

Length sums the trail as the community maps it, not a trip distance. Hike out and back and you will cover it twice; check the shape of the route before you count on the figure.

This trail is community-mapped on OpenStreetMap. Access, conditions, and maintenance are not verified by the mapper or by us. Check with the land manager before you go.

Longs Peak is about 3 miles away straight-line. We hike it, verify conditions, and keep a full guide for it.
