Two popular options within easy driving distance of Greenfield are Pinnacles Campground and Lake San Antonio Recreation Area. Pinnacles Campground has defined sites and nearby trailheads, and while some sites are best for shorter trailers, it offers a scenic base close to hiking and rock-climbing areas. Lake San Antonio provides large, RV-friendly loops with pull-through sites, water access, and developed facilities that suit longer fifth wheel stays. Both locations offer the kind of services and space that make parking, unhitching, and setting up near Greenfield straightforward for road trippers.
