This page lists all the national auto trails in the United States and Canada. For the purposes of this web site, I consider any trail that existed in at least three states "national". To get detailed information about any trail, just click on the trail's name on the list. If the trail you're looking for does not show up on this list, check the State Trails page for a list of trails found in one or two states. Trails that cross a state line can be found on the lists for both states.
