Buttermilk Campground

Well spaced campsites, reasonable privacy in most of the camp. Most sites are pull through, some are back in. All gravel but level. Concrete tables and steel fire rings in each site. Vault toilets, water taps, bear boxes and bearproof dumpsters available. Lots of trees so the sites stay pretty shaded throughout the day. There is a boat ramp with a large parking area and a couple of smaller docks for access to Island Park Reservoir. No dump station in camp but there are a couple available in Island park.
The camp hosts keep a close eye on things and will deal with loud generators, barking dogs and parties if needed. They also ask that you keep ATV's out of the camp to keep the noise and dust down.
Sites in loop B can be reserved, loop A are first come first served. The pull through sites in A are a bit larger if you have sliders. If you plan on being in the area on a weekend I'd recommend reservations. Mid week isn't quite so busy and you'll not have any trouble getting a site. Keep in mind that this area does get some of the overflow from Yellowstone National Park campgrounds on prime summer and holiday weekends so expect camp to be full during those times.

The first reviewer said what needs to be said. Att service is unusable. It’s now $20 per spot. Both loops have their own host. I liked the spots in loop A the best but they are not reservable. Pretty forested area. I’d go back.

Loop A is FF with about 12 sites. We liked it better than B with many more sites. The host let us trade reserved B site for A loop. Easy access to boat ramp and OHV trails. Pleasant, shaded setting in tall pines. Nice cool nights in summer - upper 80’s by day to low if 50. 6300’. Some campfire rings are tall - be aware.
