My son and I are seriously considering fly fishing this summer. We have never been before and are looking for a beginner-friendly company. We were looking at fishing the Snake River but I know there are plenty more places. Any help, insight, or comments would be great. Thanks.

Anyone?

When we were in Yellowstone in Sept, we saw flyfishing on nearly every river we passed. It's very popular so there are probably many good outfitters. Have you searched on Fodor's yet?

I've looked a little but nothing major. Thanks for the tip. I'll look into it.

We also saw loads of people fly fishing in Yellowstone - many in the Lamar Valley. I have never done any fly fishing, but kept commenting at how amazing it must be for these folks fishing in such a remarkable place. You should definitely check it out!

You might try inquiring on this excellent forum:

It is a great source of info on Yellowstone.

Awesome idea!
Fly fishing is a world of its own and if it's your first time you are right to get some guidance. If it is at all possible to take even ONE lesson around your home before you leave on your trip I would strongly suggest it. It will put you worlds ahead of the game and allow your guide to concentrate on getting you into some fish rather than having to teach you the basics while also getting you into some fish.
There is a guide book to fishing in Yellowstone that is sold at some concession stands that is quite exhaustive and informative. I don't remember the name though.

Check the National Park Service website of Yellowstone Park and Grand Teton NP for a detailed description of the fishing regulations.

If you’re willing to pay for a Wyoming or a Montana, or an Idaho fishing license, there are plenty of great places to fish outside the park, including a float trip down the Madison, Gallatin, Yellowstone, Snake or Henrys Fork Rivers.
When contacting any guide service, be sure to let them know up-front what your skill level is. This allows them to pair you with the right guide and put you on water that is conducive to your skills.
Although almost any flyshop in the area has qualified guides, I will suggest two gentlemen:
Walter Wiese ([email protected]) is the head guide out of Parks Fly Shop (parksflyshop.com) in Gardiner, Montana (just north of Mammoth Hot Springs). Walt can probably handle anything for you in the northern part of the park (Lamar Valley, Soda Butte Creek, etc.) and in Montana outside of the park. Even if you don’t contact him, check out their website.

Another guide I could recommend is J.D. Miller who guides out of the Henry’s Fork Anglers fly shop in Island Park/Last Chance, Idaho. J.D. guides on the Henry’s Fork and Madison Rivers, and all of Yellowstone. E-mail him at [email protected] or check the website for Henry’s Fork Anglers (henrysforkanglers.com). At present I hear that J.D. is doing some guiding in Chile but he should be back for the summer.
Both are stand up guys and great fishermen/teachers.
I'm sorry I can't give you a guides name for GTNP and the Snake River....but I'm sure Walt or J.D. could.
Hope you have a great time.
