The main trail up Whitehorse Creek valley has been used for many years by hunters, hikers and people going through to Miette Hot Springs.
The route is a favourite of equestrian users. If you meet people on horseback, step aside, stand quietly, and allow them to pass.
After passing First Whitehorse Creek Falls, the valley opens up after about 0.5 km. Ignore the first trail to the right. After crossing a broken berm, the Upper Whitehorse Creek Trail takes off to the right. (There are actually two trails but they eventually join up after a rough climb followed soon by another splitting of the trail.)
Cross the wild gravel outwash from a creek that flows into Whitehorse Creek then continue up the valley.
There is a “Y” junction after about 1.6 km; take the right fork. (The left fork goes to Sawmill Backcountry Campground).
After another km, there is a major junction (at km 7.5). The right-hand fork leads to Fiddle Pass and Miette Hot Springs. The left-hand fork goes toward Whitehorse Creek Falls.
