The Flathead National Forest Facebook Page says… It won’t be long and the hillsides will be awash with yellow larch trees. That means our Flathead National Forest campgrounds will be closing for the season soon. Take advantage to the pleasant forecast this weekend and take the family or friends out camping. For any questions call your local Flathead National Forest office, Tally Lake Ranger District 406-758-5204, Swan Lake R.D. 837-7500, Hungry Horse R.D. 387-3800, Spotted Bear R.D. 758-5376.
