This .8 mile trail is reached via the short .4 mile Cascade Creek-Falls River Cutoff Trail
which, itself, begins just south of the park on the Flagg Ranch to Ashton, Idaho NFS road (sometimes called the Grassy Lake Road) just over a mile west of Grassy Lake and 11 miles west of Flagg Ranch. The Mountain Ash - Cascade Creek Connector
provides visitors, who do not want to begin from the base of Grassy Lake dam, an alternate route to reach the Mountain Ash Creek Trail
The trail forks right from the end of the Cascade Creek-Falls River Cutoff Trail
, climbs a small rise then drops 100 feet over .8 miles to a junction with the Mountain Ash Creek Trail
, near where it crosses the Falls River.
