Elk Island is a very different type of national park. Located only 30 minutes outside of Edmonton, Elk Island is the only national park in Canada which is entirely fenced in. If this were Africa, Elk Island would probably be called a game park or a game preserve.
Game is in fact the primary purpose of Elk Island. It is the location of the genetically purest herd of bison, both wood and plains, in North America. Bison populations at Wood Buffalo National Park, Riding Mountain National Park and locations in the US all came from the herd at Elk Island. It has been an extremely important part of the attempts to bring back bison to North America.
Elk Island is one of the easiest national parks to visit in all of North America, given its close proximity to Edmonton. In addition to the game you can see in the park, it is also host to many events and concerts and is a popular destination for school groups.
