About this water

The Tree River is the planet's greatest Arctic char river — a gin-clear, boulder-strewn tundra stream to Coronation Gulf that grows the largest sea-run char on earth, the world record among them. The season is a brief Arctic summer window timed to the run, access is fly-in lodge only, and the fishing is powerful sight-casting to chrome-and-crimson char in clear pools. A true bucket-list fishery.

Under the surface

The Tree River, flowing to Coronation Gulf in Nunavut, is the world's most famous Arctic char river — a cold, clear, boulder-strewn tundra river that produces the largest sea-run Arctic char on earth, including the world record. Remote, fly-in and short-season, it offers powerful sight-fishing to chrome and crimson char in gin-clear pools beneath Arctic skies.
