Mariposa County

Mariposa County is an administrative division on the western slopes of Sierra Nevada, encompassing forests, valleys, and hillsides throughout the area. The region features numerous hiking trails and access points to the mountain landscape.

The county was established in 1850 during the California Gold Rush and still houses its original courthouse from 1854. This building remains the oldest continuously operating judicial building in the state.

Residents maintain deep ties to their mountain setting through local markets and gatherings that celebrate regional crafts and farming traditions. These community events shape daily life and reflect how people here preserve their way of living.

Visitors should bring layers and warm clothing, as elevation and season strongly affect weather conditions. It helps to check road conditions before driving through the mountainous terrain.

The area has no incorporated cities and no traffic lights, preserving genuine mountain living. This rarity makes it an unusual example of rural America in its most natural form.
