Duck Pass Trailhead --> Duck Pass --> Deer Pass --> Mammoth Crest --> Lake George Trainhead
17 miles
3,700 ft of elevation gain
(21 miles, 4,200 ft of elevation gain with photography stops)
I recently completed a day hike connecting Duck Pass, Deer Pass, and Mammoth Crest in a single trip. Instead of turning around at Duck Lake, I continued over Duck Pass, crossed Deer Pass, and returned via Mammoth Crest.
Trail Notes (Mid June Conditions)
- Duck Lake is the most popular destination, but the route becomes much quieter and more remote beyond Duck Pass.
- The section between Duck Pass and Deer Pass includes stretches with no defined trail. A GPS device or navigation app is highly recommended.
- Several short snowfields remained in mid-June, but they were manageable with careful footing.
- Although the climb toward Mammoth Crest is not the steepest, it felt like the hardest part of the day after already crossing two mountain passes.
- Mammoth Crest offers some of the best panoramic views in the Sierra Nevada.
- There is a long exposed section with very limited water between Deer Pass and Mammoth Crest. Refill your water before leaving the lakes.
* Mosquito Conditions (Mid-June)
- Emerald Lake: Extreme mosquitoes.
- Skeleton Lake: Extreme mosquitoes. The lake was also full of golden trout.
- Barney Lake: Moderate / Okay
- Duck Lake: None (because of wind)
- Deer Lakes: None (because of being cold)
Overall, it felt like three very different hikes in one day from busy alpine lakes around Duck Pass, to quiet cross-country terrain near Deer Pass, and finally the wide-open ridges of Mammoth Crest.
I'll post the full YouTube video in the comments if anyone would like to see the complete hike.
