Yosemite Mariposa County
Mariposa County, known affectionately as the “Mother of Counties,” was one of California’s original counties created at the time of statehood in 1850. It initially encompassed one-fifth of the state, but over time pieces of its territory were ceded to 12 other counties.
Today, Mariposa County’s eastern extremes comprise the central portion of Yosemite National Park, with Highway 140, the main artery, leading to the preserve’s El Portal entrance. Dog-friendly lodging, chow, hikes, water, activities and local services abound in the towns along Highways 140 and 49 and throughout the rest of the county.
