Yoho National Park was established in 1886 and is located in the Canadian Rocky Mountains along the western slope of the Continental Divide in southeastern British Columbia.
Yoho covers 1,313 km? (507 mi?) and it is the smallest of the four contiguous national parks (NP). Yoho, together with Jasper NP, Kootenay NP and Banff NP, along with three British Columbia provincial parks?Hamber Provincial Park, Mount Assiniboine Provincial Park, and Mount Robson Provincial Park?form the Canadian Rocky Mountain Parks World Heritage Site.
The park's administrative and visitor centre are located in the town of Field, British Columbia, beside the Trans-Canada Highway.
Yoho, named for a Cree word expressing awe, is a park of rock walls, waterfalls and glacial lakes. It's a park with snow-topped mountain peaks, roaring rivers and silent forests. It's a park whose history is bound up with a railroad: spiral tunnels inside mountains and stories of runaway trains.
Yoho's craggy peaks and steep rock faces posed an enormous challenge for Canada's early explorers. The mountains that were the curse of railway builders are responsible for the park's many waterfalls including Laughing Falls, Twin Falls, Wapta Falls and one of Canada's highest at 254 m (833 ft.), Takakkaw Falls. Silt carried by streams from melting glaciers high on the mountains is responsible for the deep, rich turquoise colour of Emerald Lake and Lake O'Hara.
Water is responsible for creating a natural rock bridge over the Kicking Horse River. Torrents have worn through a solid rockbed leaving a flat-rock bridge. Water erosion has also formed another Yoho marvel: balanced boulders on tall pillars of glacial till, called Hoodoos, found in the western end of the park.
