Anglers and history-focused travelers use Southside RV Park as a working base in Dillon, with Lewis and Clark sites, the Bozeman Trail's Virginia City, and the broader Yellowstone-area national parks all within reasonable driving range. The park sits just off I-15, making it a practical overnight stop on a longer route through southwest Montana. Sites are flat gravel pull-throughs, most with grass and a picnic table, and the front sites back up to a creek. Shade coverage is solid across most of the property.
Cleanliness comes up repeatedly across reviews, and it's the detail campers mention first. Aaron L. notes the bathrooms and showers are "very clean with a good amount of hooks," and that specificity reflects what multiple visitors have observed. The owner has a hands-on approach, personally walking guests to their sites and fielding questions about nearby restaurants, some of which are walkable from the campground. Sites are spaced with enough room that the park doesn't feel compressed even when it's moderately full.
Full hookups are available with electric, water, and sewer connections, and the park accommodates RVs up to 85 feet. WiFi is on-site, but at least one reviewer found it unreliable enough to recommend bringing your own connectivity as a backup. A dump station, showers, and laundry round out the facilities. One practical note: the campground sits near a railroad track, which some visitors mention as a noise factor.
Reservations are accepted and worth booking ahead, particularly during summer months when the park can fill. The season runs March through December. Campers exploring camping near Dillon will find a few other options nearby, including Beaver Head RV Park & Campground and Beaverhead River RV Park. For a stay here, calling ahead rather than relying on walk-in availability is the more reliable approach, especially during peak travel weeks in July and August.
