Mirror Lake & Crater Lake Colorado Hike Guide
Mirror Lake & Crater Lake are a pair of alpine lakes located in the Indian Peaks Wilderness in Northern Colorado. These lakes are famous due to the striking mountain, Lone Eagle Peak, which sits behind them. In order to get to Mirror Lake & Crater Lake a long hike, trail run or backpacking trip is required. While there are two approaches to Mirror Lake & Crater Lake, this guide will focus on the West, Cascade Creek/Monarch Lake, approach which does not require a reservation.

Summary
Dogs: This is a dog friendly trail but it is in a Wilderness Area, along with being notorious for having lots of moose. Please for the safety of your dog, keep it leashed at all times.
Camping: Backcountry camping is possible along the trail but a permit is required. You will need to either have a Cascade Creek (if not camping at the lake) or Crater Lake permit. Information on how to obtain one of those can be found above. In addition to backcountry camping there is a nearby campground, Arapaho Bay and more elevated lodging at Arapaho Valley Ranch.
Water: Water is plentiful along this route – you should never need to carry more than a liter.
Make it a Loop: There are endless options to extend a trip to Mirror Lake and Crater Lake, the most popular would be: adding Lone Eagle Peak or going up to Buchanan Pass or Pawnee Pass. Any additional options you decide to do turn this day into 20+ miles.
Hike Tip(s): Flowers, Waterfalls, Reflection on Lake
If you want your best chance to see wildflowers, head to Mirror Lake & Crater Lake in the early Summer (early July) as it will also be the time when the waterfalls and cascades are the best. There will never be a “bad” time to but I feel this is the best.
Mirror Lake gets its name due to the reflection of Lone Eagle Peak that happens on the water. For your best chance to get this view – pick a day that is windless and shoot for early morning or late afternoon for your best chance at the reflection photo.
Trail X Factors: Moose & Bugs
There is a lot of water along the trail to Mirror Lake & Crater Lake. This means that moose love this area and mosquitoes love this area. If you see a moose, give them plenty of space especially in the early Summer (calving season) or Fall (mating season). You do not want to get close to a moose during these times. If traveling to these lakes in the Summer, be sure to bring lots of bug repellent as the bugs can be quite bad, especially if there is a windless day.
Best Views: The trail to Mirror Lake & Crater Lake is truly one of the best I have ever been on, especially in Colorado. This is a gem of a hike and the views are great from start to finish.
