From its origin at a junction with Longs Peak Trail, this trail contours gently along the south face of Mills Moraine. The gentle positive grades give way to equally gentle negative grades before the trail shows its second, and much more drastic character.

After crossing the upper reaches of the Roaring Fork River, at roughly mile 0.7, this trail begins to climb very steeply. This short but strenuous pitch proves well worth the effort as you are quickly rewarded with the absurd views at Chasm Lake.

From the lakeshore, you'll be able to view the majestic "Diamond," one of the steepest and most iconic rock faces in Colorado. Located on the east face of Longs Peak, The Diamond rises roughly 900' straight up.
