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. Dress for the weather during all seasons by making sure you have warm, water proof clothing!

If you plan to travel in privately owned areas, like the National Historic Area on Mount Ballyhoo, you will need to obtain a land permit from the Ounalashka Corporation. See Fees and Reservations for more information about permits. Also, the National Park Service Walking/Driving Guides provide useful information regarding privately and publicly owned areas of the park.

Maine ocean islands provide the only nesting sites for Atlantic puffins in the United States. Eastern Egg Rock in the midcoast region, Seal Island and Matinicus Rock at the mouth of Penobscot Bay, and Machias Seal Island and Petit Manan Island off the downeast coast provide habitat for more than 4,000 puffins each summer.
