Glacier National Park

Glacier National Park is a United States National Park and a UNESCO World Heritage site that is on the northern border of Montana in the United States of America.

Glacier National Park is a stunning display of the geological processes that changed North America over the last billion years. The rock formations in the park are almost entirely sedimentary, laid down between 1600 to 800 million years ago when this area was an inland sea. They were uplifted during the formation of the Rockies beginning around 170 million years ago, and today contain some of the best Proterozoic fossils in the world. The mountains were carved into their present form by the advance and retreat of glaciers during the last ice age, and the park, as its name suggests, contains an abundance of glacial features, including lakes, valleys, and remnant glaciers (although these have diminished significantly in the last century).

Getting around the different parts of Glacier National Park is easiest by car, although some shuttles and tour buses do run inside the park, particularly on Going-to-the-Sun Road. Shuttles can be relatively expensive ($8 for each major segment of the routes, which connect the Belton Chalet to St. Mary's Visitor Center and even cross the border to enter Waterton National Park in Canada, where they terminate at the famous Prince of Wales Hotel. Red tour buses called Jammers (so named after the old practice of jamming the gears in place to climb steep hills) are much more expensive but a beloved fixture of the park to many tourists. They have now been modernized to run on natural gas.

The National Park Service also operates free shuttles along the Going-to-the-Sun Road. These shuttles run every fifteen or thirty minutes. However, intervals may differ depending on road construction.

Visitors without cars should acquaint themselves well with the shuttle schedules before setting out as they run infrequently and often fill up fast.

Bicycles are restricted to bike paths, roadways, and parking areas. Check the National Park Service's Glacier website for path, and road closures. Bikes are forbidden on trails. Bicycle rental is not available in Glacier National Park. It is possible to bike the length of Going-to-the-Sun Road, but the park limits bike access during peak traffic hours since many portions of the road do not have shoulders. The best times of day to go are the early morning or late afternoon. Although it is easiest to bike the road from east to west, be prepared for a steep elevation gain as you approach Logan Pass and cross the Continental Divide from either direction.
