Cathedral of Saint Augustine
Mother church of the Diocese of Tucson, this downtown cathedral wears a 1928 cast-stone façade inspired by the Cathedral of Querétaro, Mexico, decorated with yucca and saguaro blossoms and a depiction of Mission San Xavier del Bac.
Picacho Peak State Park
Between Tucson and Casa Grande off I-10, the park surrounds 1,500-foot Picacho Peak, site of the 1862 Battle of Picacho Pass. Expect hiking trails, a campground, and spring displays of Mexican gold poppies.
Sonoran Desert National Monument
Created in 2001, this BLM monument protects saguaro forests across the Maricopa, Sand Tank, and Table Top mountains. Traces of the Juan Bautista de Anza and Butterfield Overland trails cross it, and hikers, campers, and stargazers find three wilderness areas.
Yuma Desert
South of Yuma along the Mexican border, this low Sonoran Desert plain is a sweep of sand dunes and sandy soils, including the Yuma Dunes, where rare plants such as sandfood grow and flat-tailed horned lizards and fringe-toed lizards live.
El Vizcaíno Biosphere Reserve
Mexico's largest protected area spans the middle of the Baja peninsula and contains Ojo de Liebre and San Ignacio lagoons, a UNESCO World Heritage whale sanctuary where gray whales come to breed.
Tres Vírgenes
Rising above the Gulf of California in Baja California Sur, the Tres Vírgenes complex links three volcanoes, El Viejo, El Azufre and La Vírgen, which the Smithsonian describes as the only large stratovolcanoes in Baja California.
When you get to Santa Rosalía
On the Sea of Cortez about halfway down the Baja California peninsula, Santa Rosalía grew up around copper. A French company, El Boleo, mined here from 1885 until 1954, and the town still shows that past in its French-inspired wooden buildings and a prefabricated metal church. It is a Pueblo Mágico, about 73 kilometers (45 miles) east of San Ignacio on Highway 1.
- Iglesia de Santa Bárbara: Installed in late 1897, this prefabricated church of bolted metal plates is popularly attributed to Gustave Eiffel, though that authorship remains disputed. source
- Stained glass of Santa Bárbara: Inside the metal church, detailed blue and brown stained-glass windows frame the religious imagery. source
- French-era wooden houses: Clapboard and wooden buildings from the El Boleo mining years give the downtown a look that recalls its French heritage. source

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.
