Henrys Lake State Park is a state park on the south shore of Henrys Lake near Island Park, Fremont County, eastern Idaho, managed by Idaho Department of Parks and Recreation. Located only 15 miles from the West Entrance of Yellowstone National Park, the park features campground with RV hookups and camping cabins on the lakeshore, world-class fishing for trophy Yellowstone cutthroat trout, eastern brook trout, and rainbow-cutthroat hybrids (cutbows) — one of the premier trophy trout fisheries in the Rocky Mountain West, a boat ramp, dock, and fish cleaning station, mountain views of the Continental Divide and Centennial Mountains forming the Montana border, wildlife viewing for moose, elk, osprey, and bald eagles in the surrounding wetlands, a strategic base camp for Yellowstone visitors avoiding the crowds and high prices inside the park, and a quintessential high-mountain lake experience at 6,472 feet elevation surrounded by sage meadows and conifer forests.
The trophy trout fishing at Henrys Lake is legendary — cutthroat trout regularly exceeding 5 pounds and occasional fish over 10 pounds make this one of the most productive trophy trout lakes in the western US. The cutbow hybrids combine the beauty of cutthroat markings with rainbow fighting ability.
As a Yellowstone gateway, Henrys Lake offers what the packed campgrounds inside the park can’t — availability, affordability, and solitude. A 20-minute drive puts you at Yellowstone’s West Entrance while you camp lakeside in relative peace.
