About Somerset Island (Nunavut)

Somerset Island is a large, sparsely inhabited island in the Canadian Arctic Archipelago, within the territory of Nunavut. It comprises extensive tundra, coastal inlets and marine shorelines that support Arctic wildlife.

The island is mostly unpopulated and is visited seasonally by hunters, researchers and occasional Arctic expeditions. It contains archaeological traces of prehistoric Inuit cultures and is noted for its remote, low-arctic landscapes.

European exploration and intermittent use for hunting and scientific work shaped the recorded history of the island, but it has no permanent urban settlements. Marine access is seasonal and over-ice travel is common in winter.

Geographically it lies within Nunavut’s arctic region among other large islands of the Canadian Arctic; the nearest small communities are the scattered Inuit settlements of the broader Kitikmeot and Qikiqtaaluk regions, reachable only by air or seasonal sea routes.

  • Wildlife and habitats: Large uninhabited Arctic island with significant tundra and marine-influenced habitats, important for polar wildlife and migratory seabirds.

Tips for Visiting Somerset Island (Nunavut)

  • Somerset Island is extremely remote and reachable only by chartered vessel or aircraft during the short Arctic summer - coordinate logistics with experienced Arctic operators well in advance.
  • There are no facilities or services on the island; plan for full self‑sufficiency, reliable communications (satellite), and polar‑bear safety measures if you plan shore visits.
  • Timing is critical: shore access depends on sea‑ice and weather conditions, so expect itinerary changes and limited landing windows.
