Mission San José is located in Fremont, California (East Bay, Alameda County), near the junction of I-880 and CA-238.
The restored adobe church (rebuilt 1980s after 1868 earthquake) hosts Mass. The museum displays mission-era artifacts, Ohlone history, and agricultural exhibits. The surrounding grounds include olive orchards, a rose garden, and picnic areas. It's a quiet, evocative window into California's mission period.
