Located just 15 miles west of Yellowstone National Park, this high mountain lake is the kind of place fishermen dream about. The state park, named after explorer Major Andrew Henry, opens the Thursday before Memorial Day and closes mid-October, weather permitting. Anglers fish for cutthroat, brook and rainbow-cutthroat hybrid trout. The park has a modern fish cleaning station near the boat ramp. Camping is at one of 44 sites and there are camping-cabins also available for rent. During winter, information on Henrys Lake can be obtained by calling Harriman State Park.
