Reservations are available at Sawtelle Mountain Resort, a full-service RV and tent campground in Island Park, Idaho, open from May 1 through October 15. The resort accommodates rigs up to 40 feet with electric, water, and sewer hookups, and the wooded grounds also include tent sites with grassy areas and shade trees. A grocery store and gas station sit directly across the highway, making resupply straightforward. Campers planning a Yellowstone trip often use this location as a base, and places to camp near Macks Inn give a sense of what else is available in the area.
Site density is one of the more consistent themes across reviews. RV spots are tightly packed, and fire pits on some sites sit close to neighboring campsites. The tent area offers more breathing room. On-site amenities include an indoor pool, hot tub, game room, and laundry, though laundry access is restricted to pool hours, roughly 10am to 10pm. Firewood is available for purchase on the grounds.
Multiple reviewers noted water quality issues during summer 2021, when E. coli was detected and tap water was not safe to drink. That situation appears to have been specific to that season, but it is worth confirming water status at check-in. Barbara R. describes the showers and bathrooms as "really nice and clean," though experiences have varied across visits. Nearby alternatives include Yellowstone Adventure RV and Huckleberry Retreat if you want to compare options before booking.
