The Hike: Long Lake Loop Hike

From the Long Lake Trailhead, it's an easy and short 0.3-mile hike to Long Lake. Returning via this trail makes this a 0.6-mile out-and-back trip. However, to really take in the best of the Rocky Mountain Scenery, we recommend doing the full 1.5-mile loop.

Having reached the northeastern edge of Long Lake, head south over a footbridge and pick up the Jean Lunning Trail. The Jean Lunning trail travels alongside the southern perimeter of Long Lake and offers stunning views of the jagged mountain peaks surrounding the lake. Eventually, the Jean Lunning trail will intersect with the Pawnee Pass Trail. Take a right on the Pawnee Pass trail to head east and back to the short connector trail that leads back to the trailhead.
