Henrys Lake is a small, shallow alpine lake, approximately 8sqmi in area, at in length and in width. It is located at 6472ft above sea level in the mountains of southeastern Idaho in the United States. It is on the southwest side of the Henrys Lake Mountains of northern Fremont County, approximately 2 miles south of the continental divide along the Montana state line, just west of Targhee Pass. It is 16 miles due west of the western boundary of Yellowstone National Park. The lake is located in Caribou-Targhee National Forest. Springs are found around the shoreline at Staley Springs, Pintail Point, Kelly Springs, the Cliffs, and along the northshore of the lake. Inlets are found at Timber Creek, Targhee Creek, Howard Creek, Duck Creek, Hope Creek, and Kenny Creek. The lake provides the headwaters of the Henrys Fork, a tributary of the Snake River. The lake lies less than across the continental divide from the headwaters of the Missouri River in southwestern Montana.Using our international travel planner, Idaho attractions like Henry's Lake State Park can form part of a personalized travel itinerary.
A dam built at the outlet of Henrys Lake in 1923 dramatically increased the surface area of the lake.
The area surrounding Henrys Lake has been inhabited by Native Americans for centuries. During the Nez Perce War and following the Battle of Camas Creek near what is now Kilgore, the Nez Perce tribe proceeded eastward toward Yellowstone. After receiving word that the Nez Perce had entered the wilderness area, General Oliver O. Howard rested for several days on the side of the lake. To this point, Howards troops had marched every day for 26 days at an unusually quick pace.

Great campground. Very clean, lots of space between sites, excellent camp hosts. Close to Yellowstone National Park (15 min) without having to pay $70+ for a campground where your neighbor is on top of you. Campground has beautiful view of Henry's Lake and surrounding mountains. Well worth the money. Highly recommended.
Great campground with lots of space between campers. The Rangers are very nice. The area is gorgeous with lots of wildlife around. Loved watching the birds circling above the lake in the late afternoons. The grounds, bathrooms and showers are well maintained. There's good water pressure for a real shower and plenty of hot water. There's good fishing, but not many water sports. The only reason this pristine spot didn't get a 5-star is because the lake has leeches, so there's no swimming or playing in the shallows
