The park has over 700 miles of hiking trails.
Weather in the mountains can be fickle. Visitors may experience temperatures high into the 90s with clear and sunny skies, and then see snow showers and falling temperatures all in the same day.
There are six peaks over 10,000 feet high in Glacier - Cleveland, Stimpson, Kintla, Jackson, Siyeh, and Merritt.
The famed Going-to-the-Sun Road, a National Historic Civil Engineering Landmark, traverses through the heart of the park.
The area was designated a National Park by President William Howard Taft on May 11, 1910.
