Henrys Lake State Park is at 3917 E. 5100 N., about 15 miles west of Yellowstone National Park. With more than 80 camp sites, four miles of biking and walking trails and fields of wildflowers as far as the eye can see, the 585-acre Henrys Lake State Park would be amazing without the lake. But the high mountain lake full of cutthroat, brook and cut-bow hybrid trout is what makes it a jewel for fisherman who flock to this site. Water sports enthusiasts and campers are also fans - but so are the mosquitoes, so bring plenty of bug spray. .
