Several RV-friendly parks serve travelers based in Mill Valley, offering options for overnight stays and resupply. Marin RV Park provides full hookups and pull-through sites that accommodate larger coaches, plus easy access to fuel and supplies. San Francisco RV Resort also offers full hookups and spacious sites with on-site amenities well-suited to extended stays in a big rig. For a backcountry experience, Kirby Cove Campground has primitive sites and dramatic views, but no hookups and tighter access that make it better suited to smaller rigs or careful planning.
