Most people enjoy taking the Road to the Sun at Glacier National Park, we have done it three times and each time was great. Loved it. Your challenge will be to drive up the Road to the Sun without driving off the road because the sights are so beautiful however, if you go online and book a tour on one of the Red Bus you will enjoy it tremendously. They have professional drivers using old national park vehicles that have been rebuilt and modified for today’s needs. The drivers share a lot of history and pull off at all the best photo ops. I strongly suggest you use the red car for the best enjoyment of the park.
If you know when you will be at the park book your red bus as soon as possible to be sure to get a seat. Enjoy.
