At the heart of Ivvavik National Park lies the Firth River, a world class whitewater river of exceptional beauty and diversity. The headwaters of the Firth are located in the Arctic National Wildlife Refuge, Alaska, but the river is not navigable until Margaret Lake in Ivvavik. From there, the river descends for 130 kilometres, joining the Arctic Ocean at Nunaluk Spit.
The Firth River is a remote Class IV wilderness river with cold water (4-7 °C), strong eddy lines, 45 kilometres of canyon and limited rescue assistance. Private groups must be experienced Class IV rafters or kayakers, strong wilderness travellers, and be able to deal with emergencies and self rescue in a remote arctic setting.
There are numerous Class III and Class IV rapids along the river. Flash flooding is always a potential hazard after heavy rains or rapid snowmelt, as a consequence of the permafrost preventing drainage of water into the soil. Please see the Hazards page for more information.
If you are concerned about your ability to complete such a trip, there are a number of licensed outfitters offering guided rafting trips down the Firth River.
See below for list of outfitters.
