How we put this guide together
Wayro calculates the route from OpenStreetMap road data; mile numbers are positions along this route, not highway markers, and "from the route" distances are straight-line, so the real detour depends on access roads. Stops are chosen from parks, natural sites, museums, historic sites and attractions close to the route: at least one strong stop for each stretch of the drive, then the best-known places nearest the road, up to nine in all. Places that are closed, private or not open to visitors are removed. Place descriptions are written by the Wayro team from official park, museum, tourism and government websites and other published sources. Safety levels and entry rules were checked against the U.S. Department of State on October 10, 2026. Conditions change, so check the linked sources before you travel.
