Glacier National Park is all about towering peaks, massive glaciers, and driving the Going-to-the-Sun Road while mountain goats watch from the rocks. Summer is peak season, which means you need to lock in your plans early if you want to see it without scrambling for a campsite three hours away.
A typical trip runs about $1600 once you factor in gas, food, lodging, and park passes. Spreading that cost out over time makes it easier to swallow, but you need a solid plan so you are not left paying interest when summer ends.
That 0% intro window is a deadline, not free money. If you still have a balance left when the 15 months are up, interest hits the remaining amount hard.
