How we put this guide together
Wayro calculates the route from OpenStreetMap road data; mile numbers are positions along this route, not highway mile 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 (roughly 2 to 7 miles depending on the type, farther for World Heritage sites): at least one strong stop for each stretch of the drive, then the best-known places nearest the road, with no more than five of one type, up to nine in all. Places that are closed, private or not open to visitors are removed. Place and city 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 September 29, 2026. Conditions change, so check the linked sources before you travel.
