The Most Efficient Way to Visit All 48 Contiguous States

The Best Cross-Country Route, According To Science

One special Michigan State University doctoral student, Randy Olson, was called upon by Discovery News to construct a map that would not only show potential roadtrippers the best way to go through every state on the contiguous United States, but find the most efficient way to do so!

The team made sure that the stops were either at National Natural Landmarks, National Historic Sites, National Parks or National Monuments, to have the best all-encompassing view of the United States!   The road trip Randy and the Discovery team designed is perfect for anyone wanting to see our incredible country firsthand.   Randy Olson's algorithm came up with a complete trip around the U.S. in only 13,699 miles.   Please click on his blog above (link to original article) for an explanation.



Following the map, these are the cities and attractions you'll pass by along the way:

If you're more of a city slicker, the road trip above may not look very appealing to you because it involves spending a lot of time outdoors.   But don't worry, Randy Olson created a second road trip that stops at the TripAdvisor-rated Best City to Visit in (almost) every contiguous U.S. state.

This road trip will more-or-less follow the same path as the major U.S. landmarks trip and covers a slightly shorter 12,290 mile route.   You may note that cities from North Dakota, Vermont, and West Virginia are missing, so you don't really visit all 48 contiguous states.   Out of the top 400 recommended cities to visit on TripAdvisor, none were from North Dakota, Vermont, nor West Virginia.
