Glacier is a landscape of pristine forests, alpine meadows, rugged mountains, and spectacular lakes, with more than 700 miles of trails that make it a hiker's paradise for adventurous visitors seeking wilderness and solitude. Historic chalets, lodges, and the famous Going-to-the-Sun Road evoke earlier days. Glacier's weather is highly variable and can be extreme, with warm sunny summer days and winter temperatures that can fall well below freezing. Its geography, straddling the Continental Divide, brings together two very different climates, as warm, wet Pacific air moves in from the west and cold, dry Arctic air comes from the northeast, meeting at the Divide.
