The best time to visit the park is May through October, but the park is open year round. Visitors may access the area at any time but overnight camping is not permitted. The Aleutian World War II National Historic area can be accessed in the summer via an unimproved gravel switchback road from the city of Unalaska. In the winter you'll need snowshoes or skis.
