Dog-friendly Mammoth Rock Trail in Mammoth Lakes, Mono County, is a picturesque hiking destination in the Eastern Sierra region. This trail, initially following the path of an old jeep road, transitions into a scenic single-track that guides visitors through a forested slope. As hikers traverse the 2.5-mile route, they will come across a clearing formed by an avalanche in 1986, providing a fascinating glimpse into the area’s natural history.

The well-maintained paths make this hike manageable for dogs with decent stamina, though the elevation gain does add some challenge. You’ll start on what feels like an old road bed before the trail narrows and becomes more intimate as it winds through the forest. The switchbacks aren’t too steep, so most dogs handle it fine, but bring plenty of water for both of you—the elevation in Mammoth means altitude affects everyone faster than expected.

That avalanche clearing is genuinely interesting to see. It’s a stark contrast to the thick forest surrounding it, and the views from that open area are worth the work getting there. On clear days you can see out across the landscape in ways the forested sections don’t allow. The trail doesn’t dead-end at the clearing either, so if your dog is still having fun and your legs agree, you can continue exploring.

The trailhead parking area is straightforward to find and typically has enough space even on busy weekends. The trail gets decent use but doesn’t feel overcrowded in the way some more famous Sierra hikes do. Because you’re at elevation and the trail is exposed in sections, start early if you’re going in summer—afternoon thunderstorms can develop quickly up here. You can access more information about regulations and current conditions through the Inyo National Forest website, which is worth checking before you head out, especially if you’re visiting during shoulder seasons.
