It is easier to get to the Aleutian Islands than the Pribilof Islands or Alaska Peninsula, because there's a regular ferry service that runs out this way.Separating the North Pacific Ocean from the Bering Sea, the Aleutian Islands are not a single sequence of islands. Actually, they're a superchain, made of up eight smaller island groups—the Andreanof, Delarof, Fox, Four Mountain,
Near, Rat, Shumagin, and Sanak islands. In all, this adds up to more than 275 islands, stretching from the Alaska Peninsula in a southwesterly arc toward Japan. The islands are volcanic in origin, treeless, and alternate between towering (and frequently smoking) volcanic cones, and high tablelands. Separating the islands is some of the wildest, deepest water anywhere: on the Pacific side of the chain the water can be more than 25,000 feet deep, and the north side's Bering Canyon is twice as long as the Grand Canyon, as well as twice as deep, bottoming out at 10,600 feet below the water's surface. The Aleutian Islands and surrounding coastal waters make up one of the most biologically rich areas in Alaska, harboring abundant seabird, marine mammal, and fish populations—and the fish feed the ships of one of the world's busiest fishing fleets.
