Mammoth Mountain's Main Lodge is at 10001 Minaret Road, Mammoth Lakes, CA 93546. The resort directs drivers from Highway 203 onto Minaret Road.
Covers both Mammoth Lakes approaches on US-395 and SR-203 to the mountain terminus — some nearby roads aren't monitored. See what's included.
The displayed status preserves both broader Mammoth Lakes paths, including their shared SR-203 connector to the Mammoth Mountain terminus. This overlay does not create or narrow destination geometry.
Minaret Road beyond the modeled terminus, lodge roads, parking areas, and other local roads are outside MountainSwitch coverage and must be verified separately. This page adds no weather verdict.
Conditions can change quickly in the mountains. This page never replaces chain requirements, closures, or official Caltrans guidance. This page presents an existing hub corridor verdict and makes no claim about the resort last mile, in-resort circulation, best-route advice, or safe-to-drive conditions.
