The East Fork Lostine Trail is generally rated as moderate to difficult. While it features a gentle, steady climb through the valley, there are also steep sections, particularly the first 2.8 miles from the trailhead.

Along the way, expect to see a falls, smaller meadows, and ponds, especially before reaching Lost Lake. Sections can have steep snow early in the season, and you might notice bent trees from past avalanches or talus fields.
