Route Description for Lone Eagle Peak
Lone Eagle Peak (located on the west side of the Continental Divide) towers over Mirror Lake with a dramatic and sharp summit of (3,633 m). The hike to the base of Lone Eagle Peak starts out at Monarch Lake Trailhead via Cascade Creek Trail. The trail follows along the north side of Monarch Lake until it veers up along Buchanan Creek.
The trail gains elevation on moderate switchbacks and joins Cascade Creek. After crossing a wooden bridge, you are met with the first of many beautiful waterfalls. Continuing along the trail, you gain additional elevation as the valley opens up to breathtaking views of the mountain range and multiple waterfalls.
Cascade Falls is the largest waterfall on this hike and is comprised of four separate waterfalls. After Cascade Falls, the trail comes to a junction and a trail marker; continue onto Crater Lake Trail. A final push up a steep switchback places you directly in front of Lone Eagle Peak and Mirror Lake. This is one of the most scenic views in all of Colorado. For an added bonus, located further up the trail is Crater Lake (a large glacier-fed alpine lake with a stunning waterfall in the far corner). Fair Glacier is to the lake’s left and Peck Glacier is to the right.
The snowshoe to Mirror Lake is on a long and rugged trail. The snowshoe is not technical, however the length and elevation gain make it a challenge for even seasoned hikers. Along the trail, be aware that there is an abundance of wildlife in this area; moose, elk, and in late-autumn and spring you may even see black bears.
Return the way you came.
