O km: Start the hike at the overflow campground/parking in Premier Lake Provincial Park, at the Yankee, Canuck and Turtle lakes trailhead. Follow directions to Yankee Lake. Instead of going first to Turtle Lake, head straight uphill to the outlet of Yankee Lake.
1.9 km: Outlet creek of Yankee Lake, an initial gain of 110 m (370 ft.). Leave the provincial park trail, step across the creek (south) and scout around for a defined trail. The trail winds around the valley bottom somewhat, and then an arduous climb begins.
9.5 km: The climb to Saddleback Ridge, N29067-E01825, at 2400 m (7,900 ft.), and back to the vehicle is a strenuous hike, taking about three to four hours one way.
