Watch humpback whales in the Gulf of Alaska and eastern Aleutian Islands, remote sub Arctic waters where humpbacks gather each summer to feed. From May to September they fatten on dense krill and herring, and this region is one of the few places on Earth to witness cooperative bubble net feeding, where groups blow a spiral of bubbles to trap fish. Reached mainly by small ship and expedition cruise, it offers wild, uncrowded encounters, best from June to July.
