The city extends along the western foothills of the mountains Cerro Uritorco and Cerro Las Gemelas to the lake El Cajón, which forms from the river Río Dolores. It centers around the highway Ruta Nacional 38. Urban development has grown from the late 1980s, encouraged by the arrival of families from other cities, especially those from Buenos Aires, Rosario, and Córdoba. Development was dominated by residential construction. The urban area has grown to include areas that still maintain predominantly natural characteristics, such as the rock formation El Zapato, the Los Paredones hills, and the banks of the Calabalumba River.
