Why Visit the Aleutian Islands?
The Aleutian Islands are perfect for travelers seeking the ends of the earth. The archipelago is part of one of the most volcanic regions on the planet, where the Pacific Plate dives beneath the North American Plate. The treeless landscape alternates between mountains, beaches, and lagoons, bathed in ever-changing light and weather.
The destination boasts a unique history: 3,000 years of Unangax culture, the Russian Orthodox presence, and the little-known episode of the War in the Pacific. It also boasts a rich variety of marine life —otters, whales, sea lions—and is a prime destination for birdwatchers. It is a challenging journey, reserved for the curious and lovers of untamed nature.
What to Do in the Aleutian Islands?
Here are the top attractions, ranging from history to nature.
1. Explore World War II sites
The Aleutian World War II National Historic Area, in Dutch Harbor, commemorates the 1942 bombing, one of the few to occur on U.S. soil. A visitor center and the ruins of Fort Schwatka on Mount Ballyhoo can be visited with a permit from the Ounalashka Corporation. A little-known chapter of the Pacific War.
2. Discoverthe Russian and Unangax heritage
The Orthodox Cathedral of the Holy Ascension, one of the oldest churches in Alaska, stands with its blue domes overlooking the bay. The Museum of the Aleutians traces 3,000 years of Unangax culture, the Russian era, and the contemporary period. A rare testament to the cultures of the Far North Pacific.
3. Observe wildlife and birds
The waters of the Aleutian Islands are home to a rich variety of marine life: otters, sea lions, seals, and whales. On land, hiking trails lead to scenic overlooks such as Mount Ballyhoo. The archipelago, largely protected by the Alaska Maritime National Wildlife Refuge, is renowned among ornithologists for its seabird colonies.
