Campfires are not allowed. Camping is prohibited in the Four Lakes Backcountry Zone from May 1 through November 30.


This route sits just in front of the Continental Divide and provides stunning views of both the Divide and its associated mountains, and the surrounding Front Range.

Due to its easily accessible nature, Mount Audubon is one of the more crowded runs in the Brainard Lake Recreation Area.

Need to Know

This is the first trail west of Brainard Lake to become passable in the Spring. It can be done without special equipment in mid to late June. It is best to get an early start. Lightning and thunderstorms are common in the early afternoon.

The Brainard Lake Road is open seasonally. During these months, a vehicle fee applies for trailheads located within the Brainard Lake Recreation Area.

Runner Notes

This can be a great high alpine run if you start early enough. Storms tend to hit this area hard later in the day. Be prepared for crowds, and please be courteous to other trails goers.


The Beaver Creek Trail enters the Indian Peaks Wilderness and climbs through the trees for
1.7 miles. Here, the Mount Audubon Trail turns left (west). Now above timberline, the Mount Audubon Trail continues to climb in a consistent manner with the exception of two somewhat steeper sections near the middle and end of the trail.

The developed trail ends at the saddle where there is a view down into the Coney Lake drainage. For the final mile and 600 vertical feet, follow the piles of rock (cairns) up the talus to the summit.

Flora & Fauna

Wildflowers, marmot, pika and moose.

This is a run to test the ankles. Very rugged terrain, but a fairly mellow ascent/descent. Views are stellar! 7.7mi

Not a favorite trail. Way too rocky.
