Yellowstone National Park

Covering an area of almost 9,000 square kilometres, its no wonder Yellowstone is so popular. Boasting lakes, canyons, rivers and mountain ranges you could spend a year here and still not see it all. Yellowstone boasts the world's largest concentration of geysers, including Old Faithful, which goes off every hour and a half. The park’s bison are the only wild, continuously free-ranging bison remaining of herds that once covered the Great Plains and are one of Yellowstone's greatest attractions.
