San Luis sits in the far southwest corner of Arizona, right on the border with Mexico. This map of San Luis prints the San Luis Library, San Luis Middle School, the Cesar Chavez Cultural Center, Moctezuma Park, Independence Park and Joe Orduño Park, from Los Alamos out to International Plaza, with the Colorado River and Río Colorado giving shape to the land.
San Luis is a city in Yuma County, on the border across from San Luis Río Colorado, Sonora.
KNOWOL made this map in 2026 and gave modern data the look of a vintage atlas. The shaded relief of the landscape comes from United States Geological Survey elevation data, and the streets were drawn from Census Bureau files. The lowest point in Arizona, 70 feet above sea level, is on the Colorado River in San Luis, where the river flows out of Arizona and into Sonora. The river’s name is Spanish for “colored reddish,” for its heavy load of silt.
A border city
Before the Spanish came, the Halywamai people lived in the San Luis Río Colorado region, and in the mid-1800s they joined the Maricopa. San Luis, Arizona, counts its beginning from 1930, when a border-crossing station opened, and two years later the United States built a brick border station in the Spanish Revival style. The two cities are contiguous. San Luis Río Colorado was once an inland port for steamboats coming up the Colorado from the Gulf of California, it became a city in 1958, and in 2020 it counted 176,685 people, the fourth-largest city in Sonora. Today the San Luis Port of Entry joins U.S. Route 95 to Mexican Federal Highway 2, and since 2010 trucks have used a second crossing, San Luis II, 5 miles to the east.
The American side grew fast. San Luis had 1,946 people in 1980 and about 20,000 by 2005, it was the second fastest-growing city or town in Arizona in the 1990s, and the 2020 census counted 35,257. Between 2006 and 2012 the city annexed more than 16,000 acres, opening land for growth in the eastern part of town. Farming, retail and manufacturing carry the economy, light industry works on both sides of the line, and the two cities share the San Luis cotton growing area.

Cesar Chavez’s country
The farm labor leader Cesar Chavez was born in Yuma on March 31, 1927. His grandfather Cesario had bought a farm in the North Gila Valley in 1906, and Chavez went on to co-found the National Farm Workers Association in 1962 and lead the Delano grape strike of 1965 to 1970. San Luis carries his name in several places: the Cesar Chavez Cultural Center, Cesar Chavez Boulevard, once G Street, César Chávez Street, once Third Avenue, and César Chávez Elementary School. The Cesar Chavez Learning Center is one of the city’s high schools, along with San Luis High School, and Arizona Western College runs a campus in San Luis. Since 2009 the city has had an independent baseball team in the Arizona Winter League, the San Luis Atleticos, which represents both San Luis and Mexico.
The San Luis Library, San Luis Middle School, Moctezuma Park, Independence Park, Joe Orduño Park, Los Alamos and International Plaza all have their places on the sheet. South of the city the Colorado passes fully into Mexico, and the Gulf of Santa Clara, at the top of the Gulf of California, lies 70 miles to the south.
This San Luis map makes a good addition to an office, library or den, and it can help teach children the geography and history of the area. It’s made for anyone who calls San Luis home, right up to the border, and KNOWOL created it in 2026 to show the city as it looks today.
