Roads get us to and through the national parks we love to visit, like the Going-To-The-Sun road pictured here, that bisects the park from east to west (or west to east) and takes us through some of the finest mountain scenery in the Lower 48 (imho).
Speaking of roads, if you are of a mind to read the latest national park news, such as the coming opening of the Tioga Road in Yosemite National Park, or the latest explosive activity at Kilauea in Hawai’i Volcanoes National Park, or where you should pitch your tent or park your RV within a national park, then go on over to the National Parks Traveler and read all about it.

Interesting article, Becky. The scenery from park roads is often so spectacular and a way for many to easily appreciate the beauty of the park. Also, the engineering and construction of many park roads is a major achievement, especially the planning required to minimize environmental impact and to maximize the scenic beauty seen from the roads.
