When you get to Hermosillo
Hermosillo, the capital of Sonora, spreads across the Sonoran Desert on Federal Highway 15. The rocky Cerro de la Campana rises right beside downtown, and stone quarried from it built the 1908 state penitentiary that now holds the regional history museum. The cathedral and Plaza Zaragoza anchor the old center, a short walk from the Government Palace.

- Cerro de la Campana: The city's landmark hill gives a panoramic view over Hermosillo, and its phonolite rocks ring like a bell when struck, which gave it its name. source
- Catedral de la Asunción: Dedicated to the Virgin of the Assumption, the cathedral on Plaza Zaragoza blends Baroque and neo-Gothic elements in an eclectic facade. source
Hermosillo Cathedral
Consecrated in 1908, the Cathedral of Our Lady of the Assumption pairs an eclectic facade of Baroque and neo-Gothic elements with a neoclassical interior; its dome was finished in 1963. A small 18th-century chapel once stood here.

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.
