What a wonderful day my husband Chuck and I had on our first fly fishing experience. GRG is a top notch organization. From booking the trip, to arriving/prepping and then meeting our guide, it couldn't have gone smoother. Our guide, Will, was patient in teaching us and was insistent in finding us a great place to fish without other distractions, Within 10 minutes, I caught a 18" rainbow trout! He instructed him while I reeled it in myself without having a clue as to what I was doing. Thank you GRGs and Will for making this the first of many future fly fishing trips!!

Reviews We've Reeled In Over The Years
My husband and I had a great time fishing with Gallatin River Guides, and our guide Connor! He had his work cut out for him as neither of us had ever been fly fishing! He was very personable, knowledgeable and had a great sense of humor. We ended up landing 5 fish! We travel to Big Sky often and plan on fly fishing again with Gallatin River Guides and will for sure request Connor.
