Mount Sir Donald is named for Sir Donald A. Smith, the famous Canadian Pacific Railway director who drove the last spike on the CPR at Craigellachie in 1885. Typical of most trails in the Illecillewaet River valley, this one was originally built by the railway as an access route for mountain climbers. Mount Sir Donald is a classic climb, and the trail leading to its base is a rigorous uphill hike. If you are looking for a way to test your wind and energy, this trail is for you.
The trail ends abruptly in a narrow rocky col between Mount Sir Donald and Mount Uto. From this notch in the wall of the Selkirks, hikers can look across to the rolling meadows of the Bald Hills in eastern Glacier National Park.
