Banks Island is a large Arctic island in the Canadian Northwest Territories, notable for tundra landscapes and important wildlife populations. It is one of the larger islands in the Canadian Arctic Archipelago.

The island is notable for extensive muskox herds, migratory birds and remote river valleys such as the Thomsen River that attract specialists and researchers. There are few visitor facilities; most travel is expeditionary and focused on wildlife observation and Arctic landscapes.

Access is limited and seasonal, typically involving charter flights or boats and often coordinated with local communities.

Named in honour of Sir Joseph Banks by early 19th-century explorers, Banks Island has been used seasonally by Indigenous peoples and later visited by European Arctic expeditions. Modern conservation measures have protected significant portions of the island.

Banks Island lies in the western Canadian Arctic Archipelago, north of the mainland and west of Victoria Island; the island’s only settlement is Sachs Harbour on the southwest coast.

  • Wildlife and remoteness: The island is remote and Arctic in character, with significant populations of muskox and breeding seabirds; access is by air or sea and facilities are minimal.
  • Settlement: Sachs Harbour is the only permanent settlement on the island and functions as a logistical base for visitors and researchers.

What to See #

  • Aulavik National Park: A protected area on the island that conserves Arctic tundra, marine shorelines and populations of muskoxen and migratory birds.
  • Sachs Harbour: A small settlement on the island's southwest coast that serves as the main community and access point for the surrounding region.
  • Thomsen River: A remote river system noted as one of the northernmost navigable rivers in Canada, flowing through muskox and bird habitat.
