We stayed for 3 nights on the North fork of the Flathead river. We had been searching around for a First come First served site and hadnt found anything that looked just right. We wanted to have a little space and be on water. We arrived at the Great Northern Flats on Thursday afternoon and found a perfect site for our Bean Trailer. It was not crowded at this point, 2 other groups camping in designated spots and a few tents tucked  under the trees by the River. I  never ventured over to check out the tent sites, but I would guess they are really nice. during the weekend days, the boat ramp, which is right in campsite area was pretty busy with people putting rafts and kayaks in. this didnt bother us, as we were out fishing or visiting Glacier National Park. The River was perfect for cooling off after being in the sun. One bathroom with no water, outhouse style. Pretty clean. We enjoyed our stay and love this part of Montana.
