Turn onto the road and drive approximately 1.5 miles to the end where the Rock Creek Pack Trail begins.
This trail runs all along the south side of Jumbo Mountain, then over a saddle on the mountain’s west ridge before joining up with the Moose Creek Pack Trail which turns in an easterly direction to run along Jumbo’s north side.
By choosing the correct point of departure from the Rock Creek Trail, you can climb Jumbo Mountain’s East Ridge, South Face, or West Ridge.
The Forest Service roads in this area are closed to motorized traffic (except snowmobiles) until May 15.
