Mariposa County, established in 1850, is located in the Sierra Nevada foothills and contains part of Yosemite National Park. Its county seat, Mariposa Town, retains Old-West charm with historic brick buildings and a tourism-driven economy. The population is under 20 000, making it one of California’s least dense counties. Homes are primarily rural — wooded parcels, ranch houses, cabins, and vacation rentals serving Yosemite visitors. Prices vary by elevation and view, averaging US $425 000 – 475 000; custom builds run US $250 – 325 per sq ft. The area is entirely rural and mountainous, roughly 1 hour from Fresno and 2½ hours from Sacramento. Residents value peace, scenery, and access to national-park recreation. Mariposa blends gold-rush history with modern eco-tourism appeal.
