Did a road trip to Wyoming this September. Spent a week in the Alpine/Afton area south of the Tetons and a couple days in the Tetons and Yellowstone. Fished the Salt, Greys, LaBarge, Hoback and Granite Creek near Alpine,the Snake in Tetons, Firehole and Madison in Yellowstone. Caught 3 species of cutthroat, rainbow, brown, brook, and whitefish. Nothing big, largest fish was a 18" whitefish, most trout were 8-16". Best fishing was in Greys River, especially the upper 25 miles (MP25-50). Lower section was heavily fished. I was surprised at how many people were fishing in the area. There were also lots of elk hunters(bow). LaBarge was a bit of a disappointment. This stream has got a lot of press lately due to a rehabilitation project for Colorado cutthroat. The upper stream was poisoned and then restocked with Colorado cutthroat and a dam was installed to prevent upstream migration of other species. This may be a good spot earlier in the season but by September there was almost no water and the only fish were holed up in the beaver ponds. Granite Creek, a tributary to the Hoback, was a beautiful area and a fun stream to explore. The Salt is right next to town and convenient. It gets heavily floated during warm weather. Difficult to wade but caught a few nice cutthroat there. Fished the Snake in Teton Nat. Park. This is a huge river and to fish from shore you have to find the smaller branches. Caught a few nice cutthroat. Incredible number of people floating and fishing here. A boat goes by about every 2 minutes. In Yellowstone, I fished the Firehole and Madison. The Madison was the only place I didn't catch anything. I only fished about 2 hours. It was hard to find a spot not being fished and the fish were too sophisticated for me. I caught a lot of fish(rainbow and brown) in the Firehole but were all small (8-12"). Stayed at 3 Forest Service cabins near Alpine: Deer Creek(Greys River), Hoback, and LaBarge. These are really good deals, especially, if have running water which Hoback and Labarge did. Don't quite understand why Forest Service would charge the same for a cabin without water as one with. LaBarge was in nicest location. Good trip.
