Treasure Hills Golf Club in Harlingen opened in 1991 and is attributed to Robert Trent Jones Sr., cited as one of his last designs. The 18-hole, par-72 course plays about 6,960 yards over rolling terrain with water on several holes and is regarded as one of the better layouts in the Rio Grande Valley. The Cristiano family acquired the club in 2024 and added a Toptracer-equipped practice range.
