I was traveling to meet up with a group of friends in Glacier NP as a stop along my solo cross country road trip. We didn't set reservations and all the campgrounds were full, so we opted to "dirt bag" it and take advantage of some free dispersed camping by the Middle Fork Flathead River. It's a popular spot for people to do this, as well as for folks to spend a day on the river, swimming and floating etc. There are plenty of large, flat spots to camp so you can usually find a place even late in the evening. A nice location with river access, incredible night skies, easy access via 15min drive to the west side of Glacier NP (photos), flat ground, perfect for a quick camp fix! Of course, it's busy and so not very quiet or private and since it's dispersed camping, there were no facilities - but we're not picky. We took advantage of the space to play some camp games, too.
