Nahanni National Park Reserve

Nahanni is the stuff of northern legend, a wilderness built around the wild South Nahanni River, which plunges over Virginia Falls (twice the height of Niagara) and knifes through four towering canyons on its way through the Mackenzie Mountains. One of the first UNESCO World Heritage Sites, it is a bucket-list river expedition into some of the most spectacular and remote country in Canada.

• Recognition: one of the first UNESCO World Heritage Sites (1978)
• Access point: Fort Simpson, Northwest Territories (fly-in)

The landscape

The South Nahanni carves through the Mackenzie Mountains in a series of deep canyons up to a kilometre high, past hot springs, tufa mounds and the thundering drop of Virginia Falls. Boreal forest, alpine tundra and karst landscapes surround the river, sheltering grizzlies, Dall sheep, mountain caribou and wolves in a vast, roadless wilderness.

Best time to go

The river season runs roughly June through September, when the Nahanni is runnable and the weather is at its (still unpredictable) best. Early summer brings higher, colder water; late summer is warmer with more settled conditions. Outside this window the North locks down in cold and darkness.

Getting there and around

There are no roads into Nahanni. Access is by floatplane, usually from Fort Simpson, landing on the river or at Virginia Falls, and travel within is by canoe or raft downstream. The vast majority of visitors join a licensed river outfitter, as running the Nahanni safely demands whitewater skill and full self-sufficiency.

Things to do

Paddling or rafting the South Nahanni, often a one- to two-week expedition, is the definitive experience, past Virginia Falls, the canyons, and hot springs. Flightseeing tours offer a shorter taste of the falls and canyons from the air, and hiking side trips reveal alpine country and sweeping river views.

Staying safe

The Nahanni is powerful, cold whitewater in a remote wilderness. Scouting, skill and respect are essential, which is why most people go with outfitters. Grizzly and black bears range the valley, weather turns fast, and rescue is far off, so carry a satellite communicator, complete the orientation, and travel prepared.

Know before you go

A Parks Canada pass and registration/orientation are required, access is by charter air, and most visitors book a licensed river outfitter well in advance. This page is a general overview, not a live conditions report; always confirm current conditions, water levels and options with Parks Canada before your trip.
