According to the United States Census Bureau, the city has a total area of 20.8 square miles (53.9 km²), all of it land.Nogales, Arizona, a crossroads community for a thousand years, wants you to experience its unique shopping, historical, and cultural adventures. The name Nogales comes from the Spanish word “walnut” and Walnut trees once grew abundantly in the mountain pass between the city of Nogales, Arizona and Nogales, Mexico.
Thousands of years ago, before European explorers ever dreamed of sailing across the Atlantic, Nogales was part of a migratory path and trade route much later called El Camino Real (The King’s Highway). Much later, regiments of armor-clad Conquistadors forayed north along this very valley in quest of precious metals and gems. Today missions built by the Spanish colonials still dot the valley’s landscape.
