Ivvavik National Park
Geography
Ivvavik contains the British Mountains which run east to west, parallel to the Arctic coast, and merge into the Brooks Range in Alaska. Draining north through the Park from the British Mountains is the Firth River, the oldest river in Canada and considered one of the great rafting rivers of the world. The river starts from year-round aufeis formations at the headwaters and then flows through extensive canyon areas before forming a huge delta as it enters the Beaufort Sea just west of Herschel Island. The first raft descent was by Martyn Williams, Alan Dennis and Jim Boyde. Gold miners have operated on the Firth River and at Sheep Creek until the area became a National Park.
On the south-east, Ivvavik National Park borders Vuntut National Park, established in 1995. Due to land claims negotiations, Vuntut is still quite undeveloped and has no roads or developed trails. Due to its undeveloped nature, several people have gotten lost and are presumed dead.
Ecology
The park contains many cultural sites of continuing importance to the local indigenous people. Protecting a portion of the calving grounds of the caribou herd, the park allows only a minimal number of people to visit per year.

On the shore of Beaufort Sea, abundant Yukon wolves, grizzly bears, and black bears inhabit the area. Other animals that inhabit this park include two species of fox, Yukon moose, lemmings, Dall sheep, gyrfalcons, muskoxen, and wolverines. The area around Sheep Creek is the northernmost extension of Dall sheep habitat in Canada. The Arctic National Wildlife Refuge lies just across the border in Alaska. The Firth River holds some of the longest stocks of Dolly Varden char in western Canada.
Activities and access
The most practical way to enter Ivvavik National Park is via charter aircraft from Inuvik, which is 200 km (120 mi) from the park. Activities such as rafting, fishing, wildlife viewing, camping, and hiking are available in the park. Rafting is available in late June to early August and rafting on the Firth River is a popular activity. A permit is required to fish in the park. There is a daily catch and possession limit of one Dolly Varden char with a restriction of three fish total. Camping is allowed in all areas of the park except archaeological sites and the park does not have any marked hiking trails.
