Traveling during the shoulder season, I found this campground nearly empty in early June. My site -- A10 -- was extra-large, quiet, and right on the lake, with super-simple access to swimming and an out-of-this-world sunset. You'll score an immense panorama of Flathead Lake and the mountains beyond by simply keeping the flaps up on your tent! I was serenaded by a pair of loons, wailing and yodeling into the night. The sites are large, and there are many that are right next to the lake -- those are the sites you want. I also highly recommend The Farmhouse restaurant in Lakeside, Montana -- just up the road -- for a supreme, healthy, farm-to-table breakfast you won't forget.
