Anyone up for a road trip? This one travels through 47 of the national parks in the U.S. and will take you two months to complete. But hey, if you’ve got plenty of vacation time saved up — why not?
The route is just under 14,500 miles, according to The Washington Post. The Optimal U.S. National Parks Centennial Road Trip map was designed to commemorate the 100th birthday of the National Park Service, which was in August of 2016, and it hit all of the national parks (at that time) in the contiguous 48 states — so it doesn’t include parks in Hawaii and Alaska, for example.
The map was created by Randal Olson, a researcher at the University of Pennsylvania. He had a little help from the Traveling Salesman Problem, which calculates the shortest route you can take to hit up a number of different cities before ending up back where you started.
National Park Service properties are constantly in flux, so it’s no surprise that some new parks have been added since Olson first put this road trip together. But you could easily add some of the new parks to the route: For example, New River Gorge National Park and Preserve, which was designated a national park in 2021, isn’t far off the route to Shenandoah National Park.

So, if you’re looking for a road trip and want to hit most of the national parks (again, excluding those in Alaska, Hawaii and other U.S. territories), then this would be the shortest, fastest way to do it. Olson recommends setting two months aside to take in all the sights.
Olson designed a circular route so that you can hop on at any point and still stay on track. To learn how the trip was calculated or to create your own trip, check out his blog.
