I had my first trip to Montana this past summer in july. I stayed at a ranch called Parade Rest Ranch In west yellowstone. It's about 6 miles outside of the West entrance of Yellowstone Natl park.Price was very reasonable I fished on the MAdison everyday that I was there. I fished under the bridge which crosses over the Madison and was about 3 miles away from the entrance to the park.The whole week I probably only saw about 6 other people fishing. Caught some nice browns and a few small rainbows. If you want to try some creek fishing I also fished in the Grayling Creek.Part of the creek is located right on the ranch,it then runs off property there will be signs. I had some success there caught some nice browns. Good Luck
