Yellowstone is endowed with immense potential. You can fly fish in this fantastic river for the longest time and still won’t exhaust what this river has to offer. As the longest undammed (and one of the healthiest rivers in the US) the Yellowstone River is a big brown trout, rainbow and cutthroat paradise. You can start your fishing expeditions from the headwaters in the Yellowstone National Park and go all the way to the waters near Big Timber.
The best way to go fishing around the Yellowstone river is float fishing. However, walking and wading can get you some good fish too. The further you head downriver, the more the brown trout numbers decline with rainbows becoming more common. If you want to catch you some cutthroat, better start fishing at the rivers in Gardiner. The best time to fish Yellowstone river is from July through October.
2. The Madison River
The Madison River is probably one of the most revered rivers in the whole of Montana when it comes to fly-fishing. If you want to get your best catch, it would be best if you took to time to learn the rhythms and the intricacies of these rivers before your fly fish trip. The waters here are dynamic, swift and loaded with huge population of rainbow and wild brown trout. Although it may seem like an uphill task to land your first catch while fly fishing in Montana, it gets easier the more you familiarise yourself with the rivers.
Furthermore, you can find the brown trout and trophy rainbow species around every bend of these rivers in Montana all year round. You can be in time for the annual salmon fly hatch to become a Madison River fly fishing legend.

4. Hegben Lake
Hegben Lake is one of the special trout fishery regions of Montana, providing a summer and winter habitat for large schools of brown trout and large rainbow trout. These fish species mostly move in and out of the Madison River to spawn. On calm day, Hegben Lake provides you with some great sight fishing for cruising risers.
Depending on what is hatching at the time of fishing, the fish may feed on tricos or callibaetis mayflies. You might want to get yourself a float tube or a pontoon boat to get to the fish. Sometimes the fish get spooky; thus, you might want to bring long leaders as well. It would be best to concentrate around Grayling or Madison arms of the lake since you might find heavy boat traffic in other parts of the lake.
