The frigid geographical environment in the Arctic has shaped the exploration attribute of the polar cruise shipping network. In this study, the typical characteristics and special structure of the Arctic adventure cruise shipping network are investigated by using the network analysis method based on the data of 172 adventure cruise itineraries in the Arctic. It is found that the Arctic adventure cruise itineraries are dominated by 8–17 days of medium itineraries, and the ratio of one-way itineraries to round-trip itineraries is about 1:1. There are differences in the centrality of different ports, forming two core ports Reykjavík and Longyearbyen and a sub-core port Kangerlussuaq. The overall contact strength of the Arctic adventure cruise shipping network is low. Under the joint influence of such factors as centrality and contact strength, the Arctic constitutes the dual-core clusters of Iceland and Svalbard Islands and a sub-core cluster of Greenland.
