Tatshenshini-Alsek Provincial Park is a remote protected wilderness area in northwestern British Columbia that conserves glacier-fed river systems, coastal-range mountains and extensive icefields. The park protects a largely roadless landscape of valleys, glaciers and braided rivers.

The area is best experienced by multi-day river expeditions, fly-in camping, or guided trips that traverse the Tatshenshini and Alsek river corridors; these waterways lead west toward the Gulf of Alaska. Wildlife such as grizzly bears, mountain goats and migratory birds use the park’s diverse habitats.

The park links with adjoining protected areas in Yukon and Alaska to form a larger transboundary conservation landscape that has been recognized for its outstanding glacial and mountain scenery. Management focuses on conserving ecological integrity while permitting low-impact wilderness recreation.

Tatshenshini-Alsek Provincial Park lies in the extreme northwest of British Columbia, bordering Yukon to the north and close to the Alaska panhandle to the west, in a remote coastal-draining mountain region.

  • Access: Remote access means most visitors arrive by air charter or extended river trips; there are few or no roads into the protected core.
  • World Heritage connection: Part of a transboundary World Heritage area that links protected landscapes in British Columbia, Yukon and Alaska for their glacial and mountain ecosystems.

What to See #

  • Major rivers: The Tatshenshini and Alsek rivers carve deep, braided channels through the park and are popular routes for multi-day wilderness river trips.

Tips for Visiting Tatshenshini-Alsek Provincial Park #

  • Most access to Tatshenshini-Alsek comes via guided multi-day rafting trips or by small aircraft/flightseeing; there are very few road entries into the park so book a licensed outfitter well in advance rather than expecting to self-drive in.
  • Plan for mid-summer visits when rivers are navigable and daylight is longest; because the area is remote, confirm pickup/drop-off logistics with your operator and expect limited on-site services.
  • If you want fewer people on the river, inquire with outfitters about shoulder-season or custom small-group departures-these are less common but reduce crowding on popular river stretches.
