Traveling to Montana, Wyoming and back to Rapid City, SD

I just noticed one thing about your route. You show your route from West Glacier to East Glacier as a direct route. There is a length limit on that route. The problem is the road goes up (the garden wall). Narrow road with hair pin turns. Do not miss it however as it is beautiful. Take your toad or enjoy even better on one of the trams/buses. To get from west to east you will need to go around the park to the south. Have a great trip as it is always beautiful.
