Aleutian Islands, Volcanic island chain in Alaska, United States.
The Aleutian Islands form an arc of more than 300 volcanic islands stretching 1,900 kilometers (1,180 miles) from the Alaska Peninsula to the Kamchatka Peninsula. Most islands are uninhabited and marked by steep cliffs, deep bays, and jagged coastlines, while larger islands also feature gentler beaches and sheltered harbors.
Russian explorers reached these islands in 1741 and later established trading posts for the fur trade. The territory passed into American hands in 1867 when the United States purchased Alaska from Russia.
The Unangan maintain their connection to the sea, visible in local markets where fresh catch and traditionally processed seafood are sold. Visitors often notice the mix of Russian Orthodox churches and traditional community halls that shape life on the inhabited islands.
Weather changes quickly and often, so visitors should prepare for wind, fog, and sudden rain even in summer. Those planning to visit inhabited islands should book flights or boat connections in advance, as these are limited and weather dependent.
The archipelago is home to 57 active volcanoes that occasionally release plumes of steam and ash as part of the Pacific Ring of Fire. On some islands, visitors can find hot springs emerging next to icy streams, offering unexpected warmth in this harsh landscape.
