The gold standard of autumn hiking in the Rockies. This trail climbs through a dense forest to reach a high-altitude valley filled with subalpine larches and the crystal-clear Minnestimma Lakes.
The Route Experience
The hike begins with a series of steep switchbacks (about 10 in total) through a forest of spruce and fir. Once you reach the valley, the trail levels out and offers spectacular views of the Ten Peaks.
- Larch Season: From Sept 15–25, the larch needles turn a brilliant gold before falling. This is the busiest time of year.
- Minnestimma Lakes: Two small tarns at the end of the Larch Valley that reflect the surrounding peaks.
Safety & Logistics
- Mandatory Group of 4: Bear activity is extremely high here. You must hike in a tight group of four or more when the restriction is in place.
- Elevation: You are at high altitude (over 2,300m). Weather can change from sun to snow in minutes.
Photography Tips
- The Ten Peaks: The classic shot is from the edge of the first Minnestimma Lake, looking back at the wall of peaks.
- Golden Hour: The larches glow most intensely in the late afternoon sun.
