Best RV Parks & Resorts near City of Rocks National Reserve
Several RV parks surround City of Rocks National Reserve in southern Idaho. City Of Rocks RV provides 24 pull-through sites with electric hookups and water connections, accommodating larger motorhomes on level ground. The park operates with 50-amp and 30-amp service options, and fire rings are provided at each site. "Sites are easy pull-thrus with full hookups. A nice little patch of grass spaces out RVs and gives each site its own outdoor space," noted one visitor about Village of Trees RV Resort in nearby Declo. Smoky Mountain Campground at Castle Rocks State Park offers RV sites with 30/50 amp power and water hookups year-round, though reviews indicate some spots may be too small for larger rigs. Heyburn Riverside RV Park features cement-bordered sites approximately 45 minutes from Twin Falls with both back-in and pull-through options.
Advance reservations are essential during peak climbing season when RV sites fill quickly throughout the area. Most parks within 30 miles of City of Rocks provide sanitary dump stations, though Castle Rocks had its station temporarily closed for repairs according to one review. Cell service varies significantly across the region, with stronger Verizon and AT&T signals available at higher elevation sites and limited connectivity in valleys. Access roads to some campgrounds present challenges, particularly for larger motorhomes. According to one camper, "The 9 miles of gravel road to get there are extremely bumpy with washboard surfaces for most of the way. In a small RV, things were bouncing around." Winter travelers should note that while Smoky Mountain Campground remains open year-round, many surrounding parks close from late September through early May.
