El Camino Real de los Tejas National Historic Trail Association

The recently designated El Camino Real de los Tejas National Historic Trail was originally established to connect a series of missions and posts between Monclova, Mexico and Los Adaes, the first capital of the province of Texas. The Trail constituted the only primary overland route from the Rio Grande to the Red River Valley in Louisiana during the Spanish Colonial Period from 1690-1821.
