The hike offers fantastic scenery stretching from wildflower meadows and dense forests and occasionally passes through or over streams to eventually access 360-degree views of an immense area on a summit of the North Cascades.

In the South Cascades forests, 8.5 miles from the town of Cougar, the Trail of Two Forests begins at the National Forest Development Road.
