Lakes & Nature

The Mammoth Lakes Basin sits in the Eastern Sierra, characterized by high-altitude glacial lakes and volcanic geology. This collection features Lake Mary, the largest in the basin, alongside Horseshoe Lake, notable for its tree-kill area caused by volcanic carbon dioxide emissions. Visitors can access the 300-foot Twin Falls via a roadside overlook or hike to McLeod Lake for views of the Mammoth Crest. The list also includes the Minaret Vista, offering panoramic views of the jagged Ritter Range.
