This is the second summer in a row that my family and I have stayed at Buttermilk. We enjoy staying here so much! The campground is beautiful and well kept, the sites are spacious and tidy, we like the fire pit. The bathrooms are pit toilets but they are kept extremely clean! Great lake acres as well. We like this campground because it's far enough away from town to be quiet but not too far away in case you need to quickly grab supplies. We look forward to visiting again!

Great location for our whole family. The campsite is near water, close proximity to food, grocery and other things that you might need, or have forgotten at home.
Quick trip to Big Springs floating. Very well maintained campground with some the best vault toilets we've experienced while camping.

I was honestly so surprised to find this little gem! We normally stay at Buffalo but so many people know about it now and it’s booked so far out and just overcrowded with people. We decided to try Buttermilk and were so happy we did! So quiet, lots of shade, and not nearly as crowded. The bathrooms looked like they had just been redone and were very clean. The camp host was so nice and it was right by the reservoir. We will definitely be coming here next time we visit Island Park.

Not heavily populated. We were some of the only guests around. You could walk up to the water near the campsite which was nice. There was also a path to the nearby boat dock that had a kayak rental. Would definitely stay here again!
