Great Waters Inn: full service fly fishing lodge on Montana's Big Hole River. Welcome to Montana's best fishing. Ace Guides of Montana is a gathering of some of the state's most experienced and competent outfitters and guides. Our approach and philosophy to our trade is simple; find and put our clients into the best fishing possible.

Ace Guides are not tied geographically to one location; we travel to the best fishing location at the time you're here. Our primary base of operations is just south of the small town of Melrose, in the heart of the Big Hole Valley. From Melrose we are less than two hours from seven major blue ribbon streams.
