North Cascades National Park is a U.S. National Park located in the state of Washington.
The park complex consists of 684,000 acres (1,069 sq mi) of the Cascade Range in four separate, yet adjoined, units: North Cascades National Park North Unit, North Cascades National Park South Unit, the Ross Lake and Lake Chelan National Recreation Areas which are managed together with the park. Several national wilderness areas and British Columbia parkland also adjoin the National Park. The park features rugged mountain peaks. Approximately 93 percent of the park was designated as wilderness in the Washington Parks Wilderness Act of 1988, which also set aside wilderness areas in Mount Rainier National Park and Olympic National Park.
