Montana is a state in the northern/northwestern United States which is characterised by diverse landscapes ranging from the towering Rocky Mountains to the wide open expanses of the Great Plains. This diverse terrain provides an ideal environment for a variety of outdoor activities including: hiking, cycling, horse riding, hunting, and fishing in summer; or skiing and snowboarding in winter. Montana is home a number of renowned national parks. These include among others: the Yellowstone National Park, one of the largest and most famous national parks in the world with more than two million acres of geysers and bubbling hot springs simmering between mountains, rivers and canyons; and the Glacier National Park, a land of mammoth mountains and ice-hewn valleys dotted with spectacular aquamarine lakes, forests, waterfalls and glaciers. What Montana lacks in big name cities, it more than makes up for in spectacular natural appeal.
