Yes, dogs are generally allowed on trails within the Mammoth Lakes Basin and Inyo National Forest. However, they must be kept on a leash at all times to protect wildlife and ensure a pleasant experience for all visitors. Always remember to pack out any waste.
The best time to hike this loop is typically from late spring through early fall (June to October), when the snow has melted, and the weather is pleasant. Summer offers lush scenery and full access to all areas, while fall brings beautiful autumn colors. Winter hiking is possible but requires snowshoes or skis and different preparations.
No, there is no entrance fee to access the Mammoth Lakes Basin or the Inyo National Forest for day hiking. However, if you plan to camp overnight in the backcountry, a wilderness permit is required. Check the Inyo National Forest website for current regulations regarding permits and fire restrictions.
The loop offers varied terrain. Sections, particularly along the Lakes Basin Path, are primarily paved and multi-use, with a moderate grade. Other parts of the broader loop involve singletrack paths, dirt, and gravel surfaces, with significant elevation changes, including steep climbs and rolling descents. You'll traverse forested areas and some rocky sections.
The loop provides breathtaking views of several alpine lakes, including Lake Mary, Horseshoe Lake, and Twin Lakes.

Portions of the loop, particularly the paved Lakes Basin Path, are considered easy to moderate and are very family-friendly, suitable for strollers and even e-bikes. This section is a pleasant way to experience the lower Lakes Basin. However, the full loop, which incorporates more rugged trails, can be more challenging and less accessible.
Yes, the route intersects with several other trails, offering opportunities for longer or alternative hikes. Notable sections include the Mammoth Crest Trail, Lakes Basin Path, and the Rim Trail. You'll also encounter parts of the Mammoth Pass Cutoff, Horseshoe Lake Trail, and Mammoth Pass Trail.
For a predominantly downhill and less strenuous experience on the paved Lakes Basin Path, consider starting from a higher elevation, such as Horseshoe Lake, and making your way down towards the North Village. The Lakes Basin Trolley can facilitate this by dropping you off at a higher point, allowing for a more relaxed descent while enjoying the scenic views.
The Mammoth Lakes Basin is home to diverse wildlife. You might spot various bird species, squirrels, chipmunks, and marmots. Deer are also common. While less frequent, black bears inhabit the area, so it's important to practice bear-safe food storage and carry bear spray if you feel it's necessary.
Along the more developed sections of the loop, particularly near the lakes and trailheads accessible by the Lakes Basin Trolley, you may find restrooms and picnic areas. However, for the more remote parts of the loop, plan to carry all the water you need. There are no guaranteed potable water sources directly on the trail, so filtering or treating natural water sources is recommended if you rely on them.
