About Mirror Lake
Reaching Mirror Lake starts with Corral Creek / Mummy Range TH and a listed one-way distance of 6.5 miles. The lake sits at 11,024 feet in Mummy Range / North Park Area, and the route is rated hard here.
The setting is very remote, comanche peak wilderness. The approach from Corral Creek / Mummy Range TH is 6.5 miles one-way and belongs in the hard tier for this guide. The north park lakes sit in quieter Mummy Range country, with longer approaches and fewer casual lake stops. The distance and setting make this a plan-ahead destination, not a casual lake stop.
NPS wilderness tables list several North Fork and Mummy Range backcountry sites from Dunraven, Lawn Lake, Lumpy Ridge, and Cow Creek trailheads, matching the longer, quieter feel of these lakes.
