About Henrys Lake Boat Access
Henry's Lake lies high in a mountain bowl (elev. 6,470 feet) 15 miles from the west entrance to Yellowstone National Park. With a backdrop of Sawtell Peak, the shallow lake is known for its trout fishery. The Henry's Fork of the Snake River originates here, just below the Continental Divide between Idaho and Montana. The South Shore Boat Access has an undeveloped boat ramp, primitive camping, fishing, and a wildlife-viewing platform. Additionally, this is stop along the Idaho Birding Trail, and a state-designated Important Bird Area. Wildlife abounds in the Henrys Lake area, including several rare species such as the white spruce, found nowhere else in Idaho. The Henrys Lake area is an important migration corridor, so if you come at the right time, you might see moose, elk, or pronghorn migrating back and forth from summer range in the highlands to winter range in the desert north of St. Anthony. We hope you enjoy your experience at Henrys Lake and take home some memories with you. If you follow “pack it in, pack it out” principles, you will help make your next visit, as well as that of others, just as special.
