In Mammoth Lakes, Mono County, the Horseshoe Lake Loop offers a straightforward way to spend an afternoon outside with your dog. Starting from the Horseshoe Lake parking area, this easy 1.7-mile trail circles the lake with minimal elevation gain, making it accessible whether you’re a serious hiker or just looking for a casual walk around water.

The trail surface shifts between native dirt and gravel, and widens and narrows from road width to single track as it winds along the south side of the lake. This variety keeps things interesting underfoot without being technically challenging. The lakeshore views are genuinely nice—the water reflects the surrounding landscape, and on clear days you get a sense of the Eastern Sierra terrain without needing to push yourself hard to get it.

Dogs are allowed on the trail, which means you can bring yours without worrying about restrictions. The gentle terrain suits older dogs or dogs still building their endurance, and the distance is short enough that even a dog who prefers shorter outings won’t feel left out. Keep water with you for both of you—the trail has some shaded sections, but much of it is open, and the high elevation means the sun feels stronger than you’d expect.

Along the way, you’ll see the typical Eastern Sierra mix of pine and aspen, plus wildflowers in season if you time it right. There’s also decent odds of seeing other wildlife, though nothing more dramatic than squirrels and birds most days. The trail connects to other paths in the area, so if 1.7 miles feels too short once you get out there, you have options for extending your time.

The parking area fills up on weekends, especially in summer, so an early start helps. Check Mammoth Trails online for current trail conditions before heading up, since the high elevation means snow can linger into early summer or return early in fall.
