El Camino Real is the historic interior road used in the early days of settling New Mexico. — The Royal Highway of the Interior Lands follows the Rio Grande River from the United States/Mexico border to Santa Fe. Designated in October 2000, El Camino Real de Tierra Adentro National Historic Trail traces the primary route between the colonial Spanish capital of Mexico City and Spanish provincial capitals elsewhere in Mexico and what is now New Mexico between the 16th and 19th centuries. The “Royal Road to the Interior Lands” introduced Europeans, their institutions, and their goods to long-established indigenous Pueblo communities as well as their nomadic neighbors. Today, the cultural corridor created along the Camino Real reflects the diverse heritages and riches of Native America, the Old World, and the modern societies of the United States and Mexico. BLM jointly administers the trail with the National Park Service.
