I couldn't capture the beauty in a picture. Such an amazing area! Would definitely return! Hopefully with more time to drink in the beauty of the area and see more wildlife!

It’s beautiful just to see but my husband loves to fish it as well.
This river is beautiful, it is wide and very clean. We drove along this River while driving through Gallatin National Forest. There were a lot of fly fishers and some tourists rafting. The water is pretty cold, but very refreshing.
