Travelers driving the roughly 250-mile stretch between the Rio Grande Valley and San Antonio often bypass the rural heart of South Texas, yet the region offers significant historical and ecological landmarks. Key stops include the King Ranch, the historic town of Goliad, and the unique geology of the La Sal del Rey salt lake.
Why the King Ranch Remains a South Texas Icon
The King Ranch, located near Kingsville, spans approximately 825,000 acres, making it one of the largest ranches in the United States. According to the King Ranch official history, the property was founded in 1853 by Richard King. It remains a working cattle ranch and a major center for agricultural research and wildlife management. Visitors can access guided historical tours that detail the development of the Santa Gertrudis cattle breed and the ranch’s role in the expansion of the American cattle industry.

Exploring the History of Goliad
Goliad serves as a critical stop for those interested in Texas colonial history. The site is home to Presidio La Bahía, a Spanish fort originally established in 1749. According to the Texas Historical Commission, the site is significant for its role in the Texas Revolution, specifically the Goliad Massacre of 1836. The nearby Mission Espíritu Santo, restored by the Civilian Conservation Corps in the 1930s, offers a look at the Spanish mission system’s architecture and its integration with indigenous populations.
The Geological Significance of La Sal del Rey
Located within the Lower Rio Grande Valley National Wildlife Refuge, La Sal del Rey is one of three major salt lakes in South Texas. The U.S. Fish and Wildlife Service identifies this site as a natural resource that has been harvested for centuries, dating back to indigenous tribes and later Spanish explorers. The lake is a "closed basin," meaning it lacks an outlet, which causes high mineral concentrations. Access is managed through public hiking trails, providing a stark contrast to the surrounding dense brushland.
Planning Your Route: Practical Considerations
Travelers moving north from the Valley toward San Antonio typically utilize U.S. Highway 77 or U.S. Highway 281.
