Located adjacent to Mammoth Pool Reservoir, Wagner's Store at Mammoth Pool is a summertime mountain retreat with a campground, general store, and cafe. Originally, the store was began by our original founders, Nelda and Waymond Wagner as as a supply post for workers building the dam at Mammoth Pool in 1957. Today, our family-run operation is still headed by the daughter and granddaughters of Nelda and Waymond, and continues the long-standing tradition of providing a fun getaway for families all over California (and the world!).
