The Gibbon River is a notable tributary of the Madison River located in Yellowstone National Park, Wyoming. Flowing approximately 79 miles, the Gibbon begins at Grebe Lake and travels through several distinctive sections before joining the Firehole River to form the Madison River. This freestone river is known for its varied water types, ranging from small headwaters and meadow sections to fast-moving pocket water and canyon stretches. The Gibbon offers diverse fishing experiences, from small brook trout in the upper reaches to larger brown trout in the lower sections, making it an excellent destination for anglers of all skill levels. While often overlooked in favor of Yellowstone's more famous waters, the Gibbon River provides quality fishing with less angler pressure, particularly during the busy summer season.
