Things To Do

Overview

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 October 31st, weather permitting. The park offers campfire programs and a Junior Ranger program. 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.

The Idaho Department of Parks and Recreation manages 30 state parks. They also run the registration program for snowmobiles, boats and off-highway vehicles. Money from registrations and other sources goes to develop and maintain trails, facilities and programs statewide for the people who use those vehicles. The agency manages a series of outdoor recreation grant programs that provide facilities and services to a wide variety of recreationists and the local governmental and nongovernmental organizations that serve them.
