Beautiful canyons, mild weather, and big fish—Thermopolis, Wyoming, is a fly fishing paradise. While Thermopolis is known for having the largest mineral hot spring in the world, this town has vastly more to offer, especially when it comes to fishing. Its shortage of notoriety and longer fishing season combine to keep fishing pressure low in the fall and spring. Scenic stretches of the river and abundant wildlife will challenge your ability to focus on the fly. Proximity to town makes for an easy morning start and a short drive to the river.
Brown trout, rainbow trout and Snake River cutthroat fill this fishery, and these fish know how to eat. Fed by Boysen Reservoir—their water flows and food source remain consistent. Hatches of tricos glitter in the air well into fall, so make sure you bring some dry flies.
