Tucked away into the unbelievably scenic Flathead National Forest, you’ll find the Lindbergh Lake campground. While there isn’t drinking water or trash pickup available, you will have access to helpful things like restrooms and food storage boxes (a must in bear country). The lake is perfect for fishing, swimming, boating, and other water-based shenanigans. This is a heavily used area, so arrive early during the peak summer season. Oh, and did we mention that your new home away from home doesn’t come with a mortgage? Yup, this is another wonderful fee-free campground.
