County-managed Marion County Park operates seasonally from April through October, accommodating RVs up to 45 feet with full hookups including electric, water, and sewer connections. The campground features recently updated sites with paved surfaces and centrally located shower facilities. Recent upgrades have improved individual sites, though some remain unlevel and may require tire blocking for proper RV setup.
Walk-up availability remains common even on weekends, as the campground tends to be less crowded than nearby alternatives. On-site amenities include fishing ponds, hiking and biking areas, children's playgrounds with a zip line swing, and a historic village offering weekend tours during summer months. Stores and restaurants lie within a short drive for campsites near Knoxville, making resupply convenient while maintaining a sense of separation from town.
