Yellow Bay State Park in Montana is one of my all time favorites. Growing up in Montana, this campground was a place my family and I always visited. Flathead Lake is such a gorgeous spot- so any camping a long the lake is perfect. Yellow Bay State Park is located on the east shore of Flathead Lake. Obviously, because this campground is located on Flathead Lake there are a lot of water activities. My family always brings their boat, and we go tubing, fishing, water skiing, and swimming. We also really love to kayak and stand up paddle board, and this is the perfect place to do it. This campground isn't very big-I believe there are 5 tent sites. There are fire pits, a boat launch and a public bathroom. The campground is pretty well kept and clean. They are pretty strict about where you dump your trash- do not burn your garbage in your fire pit. Make sure to dump your trash in the assigned garbage bins (they are bear-resistant bins). There is also a 14 day camping limit and it is open May 1st- September 30th.
