Aleutian Islands Alaska

The Aleutian Islands: The Chain That Made WWII’s Pacific Theater Geography

In June 1942, Japanese forces occupied the Aleutian islands of Attu and Kiska, the only occupation of American soil during World War II. The subsequent US campaign to retake them involved nearly 35,000 troops, brutal weather, and the Battle of Attu in May 1943, which cost over 500 American lives and killed more than 2,300 Japanese soldiers. When US and Canadian forces stormed Kiska the following August, they found it empty, the Japanese had secretly evacuated weeks earlier through the dense fog. The Aleutian campaign is rarely discussed in American WWII history, but the islands still contain the earthworks, gun emplacements, and military infrastructure of that period, largely intact in the tundra.

The Aleutian Islands stretch 1,200 miles west from the Alaska Peninsula, ending at the 180-degree meridian where east becomes west. They are among the most seismically and volcanically active chains on earth, sitting where the Pacific plate dives beneath the North American plate.

Getting There

The most accessible entry point is Unalaska/Dutch Harbor on Unalaska Island, served by Alaska Airlines from Anchorage (about 3.5 hours). Dutch Harbor became internationally known through the reality TV series Deadliest Catch, and commercial crab fishing remains the dominant industry. The island is rugged, treeless above the valley floors, and frequently socked in with weather that cancels flights without notice. Budget extra days at either end of your trip for this.

Unalaska Island

The Holy Ascension Cathedral in Unalaska is one of the oldest Russian Orthodox churches in North America, built in 1826 during the period of Russian America. The Aleut people’s conversion to Russian Orthodoxy created a synthesis of indigenous and Christian practice that continues today; services are conducted in Unangan, English, and Church Slavonic. Entry requires respectful dress and advance arrangement.

The Museum of the Aleutians in Dutch Harbor covers the full arc from pre-contact Unangan culture through the Russian period and WWII, with well-curated artefacts and explanatory materials. Mount Ballyhoo above Dutch Harbor has remaining WWII fortifications accessible by hiking trail.

Wildlife

The surrounding waters hold steller sea lions, sea otters, Dall’s porpoise, and humpback and orca whales. Seabird colonies on the outer islands include tufted puffins, murrelets, and kittiwakes in numbers that are difficult to fully register. The landscape above the waterline is tundra grass and volcanic rock with virtually no trees; this feels strange and, once you adjust, beautiful.

Where to Stay and Eat

The Grand Aleutian Hotel is the main accommodation in Dutch Harbor, a proper hotel by any standard, with the Chart Room restaurant serving fresh seafood at relatively reasonable prices given the remoteness. A halibut fillet caught that morning costs less than a comparable meal in Anchorage. Rooms run around USD 140-200 per night.

The Outer Islands

Access to the outer islands, Adak, Atka, Attu, requires charter air or sea and serious planning. Attu, the westernmost point of the US, has no permanent population and is extremely difficult to reach; birders go for Asian vagrants that appear during migration season. This is expedition travel, not casual tourism. Work through Alaska charter operators based in Unalaska or Anchorage.

Practical Notes

Weather is the governing factor. June through August has the longest daylight and marginally better odds of clear sky; expect wind, rain, and fog regardless of season. All supply chains run through Anchorage; bring what you need. The population of Unalaska/Dutch Harbor is around 4,500, and services scale accordingly.
