History

When California was formed in 1850, Mariposa County was one of the original 27 counties and covered one-fifth of the state. The County was reapportioned to create all of parts of 11 other counties giving rise to the nickname the “Mother of Counties.”

Living Here

With no incorporated cities (or stop lights), people either live in rural areas or in one of our many charming communities. They also enjoy varied outdoor recreational opportunities as the terrain ranges from grassy rolling hills to alpine-like mountains.

Present Day

Today, our county is known for friendly citizens who greet or play host to the large number of visitors who come from around the world. We are also known for our festivals and fun spirit which are enjoyed by visitors and locals, alike.
