About

Henrys Lake State Park is a hit for its stunning mountain views and proximity to Yellowstone. Campers love the clean bathrooms and spacious sites, though the lack of a working dump station is a major pain point for many. The lake is beautiful, but watch out for leeches if you plan on wading. It is a great spot for fishing and bird watching, but be prepared for bugs.
