The Camino Real de Tierra Adentro, or the Royal Road of the Interior Land, was an ancient Spanish route stretching for 2,560 kilometers (1,590 miles) between Mexico City and San Juan Pueblo (Ohkay Owingeh) in New Mexico. It was in use from 1598 to 1882, and was one of the four major “royal roads” that connected Mexico City to its tributaries during and after the Spanish colonial period.
