While the views from this hike are world-class, the difficulty required to access them is not. While you will have to drive 17 miles down a winding dirt road to reach the trailhead, the actual hike from Mowich Lake to Tolmie Peak is quite moderate. The elevation gain throughout most of the hike is very gradual.

Once you pass Eunice Lake and head toward Ipsut Pass, the grade steepens considerably. If you are beginning to tire by the time you reach Eunice Lake, it’s probably best to turn around at that point and retrace your steps to Mowich Lake.

While there is a campground at Mowich Lake, note that the area near Tolmie Peak is closed to overnight camping, and is thus only accessible via day hike.
