The proof

There are far too many possible orders to try one by one. Instead, the solver works out the least driving time any route could possibly need, then searches until it finds a route that matches it. Once it does, no faster order can exist. An independent solver then does the whole job again and has to reach the same answer.

Drive times assume no traffic and don't count time spent at each stop. How it works.

Proven optimalNo loop through these 51 stops takes less driving time.

Take it with you

GPX works in most navigation and hiking apps (OsmAnd, Organic Maps, Gaia). KML opens in Google Earth. Each stop in the files sits where a car can pull in.

Google Maps and Apple Maps only take so many stops per link, so the trip comes in parts of about 10 stops, each one starting where the last one ends.
