Discover the Hawaiian Islands on a 7-night adventure cruise. Formerly known as the “Sandwich Islands”—as named by Captain Cook following his visit in 1778—this archipelago of volcanic islands and atolls sits at the center of the North Pacific Ocean marking the northeast corner of Polynesia. The island chain forms the largest marine sanctuary in the world and one of the world’s most important habitats for humpback whales. Two-thirds of the North Pacific population migrates to Hawaii each winter for breeding, calving, and nursing. We encounter many of these same humpbacks in Alaska where they feed during the summer months.
