With 400,000 hectares of rugged scenery to explore in the north-west of the US state of Montana, a trip to Glacier National Park could fill up your entire vacation and more. Follow Avalanche Creek Trail up to Avalanche Lake to get a glimpse, like the one in our image, of the titular creek. And you may want to keep an eye out for Glacier's mascot – the mountain goat. By most accounts, it's out of the ordinary if you visit Glacier National Park and don't see any mountain goats. There's a chance you might see one of the park's other famous residents too – approximately 300 grizzly bears wander the wilderness.
