Just over the Idaho border from West Yellowstone, Island Park KOA sits along Route 20 as a drive-in base camp for Yellowstone visitors who want full hookups without the crowds and prices of Montana-side options. Sites are level gravel pull-throughs with grass on the sides, and the layout accommodates RVs up to 68 feet. The tradeoff is noise. As Terrie L. puts it, "Right off the highway, so you hear the road noise," which is worth factoring in if you're a light sleeper.
The campground runs May 15 through October 1 and provides full hookups with electric, water, and sewer connections alongside a dump station, showers, and WiFi. Shade is limited across most sites, which matters on warm summer afternoons. The bathhouse is code-secured for privacy, and the laundry facility draws consistent praise from reviewers. Cell coverage varies by carrier: Verizon users report strong signal and hotspot speeds, while T-Mobile typically holds at one to two bars.
Henrys Lake State Park Campground sits just to the west, giving anglers and boaters a nearby alternative with direct water access. Campers who want to compare places to camp near Island Park will find several options spread across the area, including Targhee Creek to the north and Bootjack Rd. to the south for those leaning toward dispersed-style sites.
The hosts communicate proactively before arrival, and multiple reviewers note staff willingness to go beyond standard service. "Above and beyond all around," writes Kelly S., who also notes the Yellowstone west entrance is under 20 minutes away. Rates run around $91 per night, which puts it at the higher end for the region. This campground works best for RV travelers using it as a staging point for Yellowstone day trips who prioritize hookups and reliable facilities over seclusion or quiet surroundings.
