Access to Bowman Lake is via a gravel road through rough terrain from Polebridge. The road winds over mountains and through valleys for a good 7 miles before arriving at the lake. There are various trails and a campsite.
But the trip is worth it for the great view of the mountains alone. If you go hiking in this area, which is blessed with bears, you will soon be alone.
But you should stock up on Bear Spray to avoid any unpleasant surprises.
