Route 83 out of Bigfork takes you through the Swan Valley area of the Mission Mountains.
I personally think this is one of the prettiest drives in Montana and even though it is only two lanes, an easy drive.
You drive around Swan Lake and Seeley Lake before you get to Clearwater Junction. At the Junction you turn left at the Big Cow.
This will take you to MT 200. From there you take MT 141 to Avon and then MT 12 to Helena.
I remember this drive quite well, although it has been some time since I've taken it.
Thanks for visiting today. I look forward to reading your comments. Have a beautiful day.
