A rafting journey down the Firth River in Ivvavik National Park is an enchanting, scenic passage from the British Mountains to the coastal tundra plains and the Arctic Ocean. Rafting over 11 river days, you'll journey 150 kilometers (94 miles) with an approximate elevation drop of 460 meters (1500 feet). This is a land of contrasts: forest and tundra, craggy peaks and alpine meadows, wild coastline and ice-filled seas. The Porcupine caribou herd, grizzly bears, mountain sheep, muskox and wolves thrive in this arctic Eden, along with millions of migratory birds. The Firth features a long canyon stretch, Class III rapids and Inuvialuit cultural sites. It’s a fly-in and fly-out rafting journey that finishes at the Arctic Ocean.
