Dillingham Ranch, formerly known as Mokuleia Ranch, served as the family getaway for generations of Dillinghams. Throughout the years, Dillingham Ranch has also hosted cattlemen, ranchers and equine sportsmen. Notable visitors to Dillingham Ranch have included Noel Coward, who authored A Room With A View while sitting on the lanai, Prince Hussein of Jordan, the Marquis of Waterford, Eva Gabor and Ginger Baker.
Additionally, Prince Charles, Major Ronald Ferguson, General George S. Patton and various international polo stars, among others, have competed on the polo field. The polo grounds are considered the birthplace of Hawaiian polo, which was especially popular in the late 1800s. Walter Dillingham cofounded the Hawaii Polo and Racing Club and played the sport until he reached the age of 65.
