The Duck Pass Trail in Mammoth Lakes, Mono County, is a dog-friendly hike for outdoor enthusiasts seeking a picturesque adventure in the Eastern Sierra. This scenic trail begins its ascent behind Coldwater Campground, winding through a forested hillside with stunning views of Arrowhead, Skelton, and Barney Lakes along the way.

The terrain varies nicely as you climb, mixing sections of dense forest with open meadows that give you breathing room and views. The elevation gain is moderate but steady, so it’s a good workout without being punishing. Dogs handle the trail well, and the cooler mountain air means you’re not dealing with the heat you’d find at lower elevations in summer.

For those looking to extend the hike, a side trail leads to Emerald Lake, offering a delightful detour or a chance to loop past Skelton Lake and Barrett Lake before returning to the main trail. The multiple lake options mean you can tailor the hike to your dog’s fitness level and how much time you have. Shorter versions work fine if you’re just doing an afternoon outing, while the longer loops make for a full day out there.

The trail is maintained by Inyo National Forest, and you should check their website for current trail conditions before heading out, especially earlier in the season when snow may still be present at higher elevations. The Coldwater Campground trailhead has parking available, which beats hunting for a spot in some of the more crowded areas around Mammoth. Bring plenty of water for your dog since much of the hike is exposed, and the alpine terrain doesn’t offer much shade once you get past the initial forest section. The lakes themselves are cold but refreshing after the climb if your dog enjoys a dip.
