If the Going-to-the-Sun Road sounds like the kind of U.S. road trip for you, it might be time to start planning your adventure. And while this 51-mile route might not be the longest on the list, that doesn't mean that you have to rush through it. You must stop and see everything along the way - including the beautiful Lake McDonald. Yes, with crystal clear water and amazing multi-colored rocks, it's a must-see.
