Located along the Canadian border in central Alaska, the preserve protects 115 miles of the 1,800-mile Yukon River and the entire Charley River basin. Numerous rustic cabins and historic sites are reminders of the importance of the Yukon River during the 1898 gold rush. Paleontological and archeological sites here add much to our knowledge of the environment thousands of years ago. Peregrine falcons nest in the high bluffs overlooking the river, while the rolling hills that make up the preserve are home to an abundant array of wildlife. The Charley, a 100-mile long wild river, is considered by many to be the most spectacular river in Alaska.

This park celebrates the Klondike Gold Rush of 1897-98 through 15 restored buildings within the Skagway Historic District. The park also administers the Chilkoot Trail and a small portion of the White Pass Trail. Included in the park is a portion of the Dyea Townsite at the foot of the Chilkoot Trail.

The Aleutian World War II National Historic Area encompasses the historic footprint of the U.S. Army base Fort Schwatka. Located on Amaknak Island in the Aleutian Island Chain of Alaska, the fort was one of four coastal defense posts built to protect Dutch Harbor (the back door to the United States) during World War II, the fort is also highest coastal battery ever constructed in the United States. In 1996 Congress designated this National Historic Area to interpret, educate, and inspire present and future generations about the history of the Aleut or Unangan people and the Aleutian Islands in the defense of the United States in World War II.

Alaska's oldest federally designated park was established in 1910 to commemorate the 1804 Battle of Sitka. All that remains of this last major conflict between Europeans and Alaska Natives is the site of the Tlingit Fort and battlefield, located within this scenic 113 acre park in a temperate rain forest. Southeast Alaska totem poles and a temperate rain forest setting combine to provide spectacular scenery along the park's coastal trail. The trail circles back along Indian River to the visitor center. Another loop trail continues across the Indian River footbridge past the Memorial to the Russian Midshipmen who died in the Battle of Sitka. The park's story continues at the Russian Bishop's House, one of three surviving examples of Russian colonial architecture in North America. This original 1843 log structure conveys the legacy of Russian America through exhibits, refurbished Bishop's living quarters and lavish icons in the Chapel of the Annunciation.
