The John Muir Geotourism Center (JMGC) is a non-profit that inspires people of all ages to explore, learn, share, and preserve the values of the John Muir Legacy. We achieve this through community programs that deliver economic, social, educational, spiritual, and physical growth.

We are located on Main Street (Hwy 132, the historic John Muir Route) in downtown Coulterville, California, in the historic Gazzolo building (a Gold Rush era saloon and dance hall from 1858).
