Formerly an important 18th-century thoroughfare created by the Spanish colonists, El Camino Real de los Tejas is a National Historic Trail that stretches across Texas for 2,580 miles from the Mexican border all the way into Louisiana. There are plenty of fascinating things to see and do along the trail, many of which can be reached by car. Highlights include a Spanish mission offering interpretive tours, a former Governor's Palace, and a scenic lookout point. Hours of operation vary from site to site. No admission fee is charged to explore the sale, but some individual attractions require payment. Map
