The King Ranch Visitor centers offers a quaint selection of King Ranch memorabilia. Numerous books regarding various King Ranch related history, cookbooks, hats, shirts, t-shirts, etc. There is also a 30+ minute video that relates some of the history of the King Ranch, its early beginnings, the expansion, and ongoing operations. Very interesting video.
We also took the history tour that last for 90 minutes. It was absolutely great.
