The North Sky trail connects North Boulder to Joder Ranch on the west side of Highway 36. This green flow trail opened on July 22, 2024. The trail is open to hikers/runners, bicyclists and equestrians. E-bikes are not permitted. Dogs must be on-leash but are prohibited from May 1 – July 31 to protect bird nesting habitat.

This trail is a direct result of much advocacy and work by Boulder Mountainbike Alliance, and BMA helped build half the trail.
