The Bering Sea has as its southern border a line running from Kabuch Point (54°48′N 163°21′W) in the Alaskan Peninsula through the Aleutian Islands to the southern extreme of the Commander Islands and on to Cape Kamchatka, in such a way that we take in all the narrow waters of the Bering Sea between Alaska and Kamchatka.

There is no doubt that the very best of this area is its marine wildlife; we will encounter sea lions, sea bears, sea apes, insular seal and a great variety of whales: sperm, killer whale, Cuvier’s beaked whale; dolphins and sea swine, Minke’s whales, sei whale, humpback whale, Pacific right whale and many other species. Bird rookeries and breeding grounds are in abundance here.
