Data tinkerer Randy Olson captured the imagination of the internet with his plan to engineer the ultimate U.S. road trip. He used an algorithm to find the quickest driving route that would stop at a national natural landmark, national historic site, national park or national monument in all of the lower 48 states.
Now Olson has performed the same computations for Europe. Picking the best places to stop is always tricky, but Olson decided to follow the 50 recommendations of this Business Insider article. He then used his algorithm to find the quickest route between the sites.
The resulting route covers 16,287 miles (26,211 kilometers) and ranges from Lapland to Istanbul. Olson says it would take 14 days to drive if you didn’t stop at all, or probably about three months to drive comfortably. You can see an interactive version of the map here.
If you have some programming chops and don’t like Olson’s choices, no problem — he has released his source code with instructions so you can optimize your own road trip.
