Best RV Parks & Resorts near Lewis and Clark National Forest
Several RV parks dot the landscape near Lewis and Clark National Forest with varying levels of hookup services. Great Falls RV Park offers big-rig friendly sites with electric, sewer, and water hookups, though spaces tend to be tightly arranged with minimal separation between units. Prewett Creek RV Park provides full-hookup sites with 50-amp electrical service in a more spacious setting along the Missouri River. "The site was nice and long, with room to park across, and hookups were well placed—electric toward the back, water and sewer mid-site," noted one camper about Prewett Creek. Helena Campground & RV Park includes market access alongside full hookup capabilities, making it convenient for resupply while traveling, though the gravel pads can require leveling blocks during wet weather.
Seasonal considerations significantly impact RV camping in this region, with many facilities operating from May through October. Great Falls KOA remains open year-round, offering all-season access to full hookup sites with both 30 and 50-amp service. Cell reception varies dramatically throughout the area, with Prewett Creek reporting limited connectivity (1-2 bars) while parks closer to Great Falls maintain stronger signals. Dump stations are available at most established RV parks, including Conestoga Campground in White Sulphur Springs, though some like Fort Harrison RV Park lack this service. For RVs requiring propane, options are limited near the forest - a camper noted that 486 Market in Cascade "fills propane tanks" alongside offering diesel fuel. Navigation to some parks requires attention to clearance limits, particularly when approaching from I-15 where bridge heights may restrict larger motorhomes.
