Sitting among tall, forested mountains, Swan Lake is more than a mile wide and about ten miles long. People interested in recreational boating should definitely check out Swan Lake in the summer, as it has great weather, beautiful surroundings, and a relatively uncrowded atmosphere. The other main activity for visitors to Swan Lake is fishing, which is great for rainbow and cutthroat trout. Fly fishing is also a possibility, for those who want to give it a try.

Swan Lake lies within Flathead National Foreset. Just a few miles west of Swan Lake is enormous Flathead lake covering more than 120,000 acres.
