11 patches across 7 counties, 2 free to enter. The season opens September 20 at Mickelson Pumpkin Patch.
11 of the 40 California patches we track are in Bay Area, spread across Alameda County, Contra Costa County, Marin County, San Francisco County, San Mateo County, Santa Clara County, Sonoma County. 8 of them run a corn or crop maze, and 3 have farm animals your kids can get close to. 11 have their 2026 dates confirmed on the farm's own site.
2 patches here are free to walk into, which makes them the low-risk option with unpredictable toddlers — you are not out $80 if the visit lasts twenty minutes.
