The park protects the majority of the Cypress Hills landscape, which consists of three separate elevated blocks of lush forest and fescue grassland surrounded by dry mixed-grass prairie. The "west block" and "centre block" are protected as provincial parks, and are managed by Alberta Parks and Protected Areas and Saskatchewan Parks, respectively. The "east block" of the Cypress Hills, situated near Eastend, Saskatchewan, is not a park or protected area. The "Fort Walsh National Historic Site" is also located adjacent to the "west block".
