Las Heras borders Mendoza City to the north, with San Martín Avenue serving as a major connecting road between the two.

The area includes the low mountain range of El Challao, home to hot springs.

The name of the city is an homage to General Juan Gregorio de las Heras, hero of the Argentine War of Independence.

Las Heras was heavily damaged in the 1927 Mendoza earthquake.
