Fillmore's compact downtown, river corridor and nearby open country make it a welcoming base for towable travel trailer travel. Campground access ranges from small RV parks to riverfront sites with hookups and pull-through spaces for easy setup. Major routes such as Highway 126 and U.S. 101 provide straightforward towing corridors and convenient places to pull over for rests. Local municipal parks, RV parks and designated campground loops offer places to park, unhitch, and set up for flexible day trips.
