Countryside RV Park

Day trips to Lewis and Clark Caverns run about an hour from Countryside RV Park, making this open, full-hookup stop in Dillon a practical base for exploring southwest Montana. The park sits just off I-15 with easy on-and-off access, and pull-through sites on a gravel road make arrival straightforward for rigs of most sizes. There are no trees. That means open sightlines toward the surrounding mountains and rangeland, but also exposure to wind, which reviewers flag as a real factor, particularly overnight.

Sites run $42-$47 per night and include electric, water, and sewer hookups, along with WiFi, showers, and a dump station. The park stays open year-round. Bathrooms are functional but compact, with curtain-style stalls that one reviewer noted feel cramped. Cleanliness comes up consistently across reviews, with james P. describing it as "a very spacious park well kept." Town amenities sit just across the interstate exit, so restocking is straightforward.

Campers passing through on I-15 will find Beaverhead River RV Park a few miles up the road if they want a riverside setting, or Barretts Park - USBR to the southwest for a more developed public option. For a broader look at campgrounds near Dillon, the area has several alternatives worth comparing depending on your itinerary. Countryside RV Park works best as a reliable overnight stop rather than a destination stay.
