Lake Gregory Regional Park features RV-friendly sites with hookups, level pads and easy access from Crestline, making it a top choice for towable Airstreams. For a more rustic option, Heart Bar Campground provides shaded, scenic sites close enough to Crestline for quick day outings, though it has fewer hookups. Several smaller county and forest campgrounds near Crestline offer pull-through sites or large turnarounds that simplify hitching and unhitching. Always check site length limits, hookup availability and reservation policies to ensure your towable fits comfortably before arrival.
