Glacier National Park was established in 1910, with one million acres of land and 25 "active" glaciers that are constantly on the move due to thawing and melting. The park contains over 700 miles of hiking trails, including "Going-to-the-Sun Road," a 50-mile walk that provides some of the most spectacular views of Montana, making it the most popular tourist destination. Located on the Canada-United States border, the park encompasses two mountain ranges, over 130 lakes, more than 1,000 different species of plants, and hundreds of animals. For a taste of true wilderness, an overnight hike through the backcountry is a great getaway. If you prefer a warm bed and a hot shower, there are four Glacier Park lodges nearby, but be sure to reserve a room ahead of time as these hotels book up fast.
