Firehole River in Yellowstone National Park, Wyoming

Follow the course of the Firehole River through northwest Wyoming and you’ll get a tour of some of Yellowstone National Park’s major geyser basins, including a pass by Old Faithful. The 21-mile-long river is known as one of the nation’s best fly-fishing spots—so much so that it’s the only type of fishing allowed in the Firehole River.

The Firehole River is located in northwestern Wyoming, and is one of the two major tributaries of the Madison River. It flows north approximately 21 miles from its source in Madison Lake on the Continental Divide to join the Gibbon River at Madison Junction in Yellowstone National Park. It is part of the Missouri River system.
Length: 21 miles (33.80 km)
