Pinnacles Campground is convenient for Greenfield visitors who want developed sites, restrooms, and close access to hiking and rock formations, though sites typically do not include electrical hookups. Lake San Antonio Recreation Area offers larger RV loops and lakeside settings with ample room for maneuvering and some sites that include hookups and pull-through options. Both campgrounds provide scenic settings and enough space to park, unhitch, and enjoy outdoor activities without tight turns or steep grades. Reserve ahead during busy weekends to secure a site near Greenfield.
