Buffalo Run Campground sits along US-20 in Island Park, Idaho, operating from mid-May through mid-October for both RV and tent camping. The facility accommodates RVs up to 65 feet with full hookups including electric, water, and sewer connections, plus amenities like showers, WiFi, and a dump station.
Road noise from US-20 affects the upper sites more significantly, while lower sites tend to be quieter and feature grass and trees alongside gravel pads. The upper area consists primarily of gravel, sand, and dirt surfaces that can become muddy during rain. Recent renovations have been underway to improve site conditions. Cell service varies considerably, with AT&T providing inconsistent coverage ranging from 1-3 bars and data speeds between 2.5 MB/s to no service. T-Mobile offers limited connectivity.
"Very helpful hosts. Clean paved site," notes one recent visitor, highlighting the management's attentive service. The campground serves as a practical base for exploring Yellowstone National Park, located about 28 miles away in West Yellowstone. Box Canyon Campground provides another option just over a mile north for campers seeking alternatives in the area.
Buffalo Run works well for RVers needing full hookups and a staging point for regional exploration, though campers sensitive to road noise may prefer requesting lower sites during reservation.
