Fishing in Nahanni National Park

Nahanni National Park Reserve sits in the southwest corner of the Northwest Territories, where the South Nahanni River cuts through some of the deepest river canyons in Canada on its way to meet the Liard.

The park is vast and almost entirely roadless — access is by floatplane or a multi-day river trip, and most anglers arrive as part of a paddling expedition rather than a dedicated fishing journey. The South Nahanni is the park's main water.

It holds arctic grayling, bull trout, lake trout, northern pike, and whitefish.

The river runs silty through much of its length, which keeps fishing expectations honest — grayling are the most reliably catchable species, and the clearer tributary mouths and side creeks are where most of the action concentrates.

Prairie Creek, Clearwater Creek, and the Little Nahanni River are among the tributaries that draw fish and anglers alike. Grayling respond well to dry flies — elk hair caddis, parachute adams, royal coachman — fished on or near the surface.

For spin fishing, small spinners like a Mepps or Panther Martin in the 2–4 gram range cover most situations. Bull trout run larger and tend to hold in deeper, colder water.

Fishing inside the park requires a Nahanni National Park Reserve Fishing Permit, issued by Parks Canada — a territorial licence does not cover park waters. The permit is specific to Nahanni and must be carried on your person while fishing.

No live or dead fish, fish parts, or live fish eggs may be used as bait anywhere in the park. Only one line, one lure, and one hook arrangement is permitted at a time. Check with the park office for current permit fees and possession limits before your trip.

The remoteness here shapes everything. There are no roads into the fishing water, no outfitters waiting at a dock.

You carry what you need, you fish water that sees few people, and you share the river corridor with grizzly bears, wolves, and Dall's sheep on the canyon walls above. That context is part of the fishing.
