Kaʻiulani traveled to the Parker Ranch at Waimea, on the island of Hawaii on December 6, 1898. The ranch owner, Samuel Parker, had served on Kalākaua's privy council, and was Liliʻuokalani's minister of foreign affairs when the monarchy was overthrown. Kaʻiulani attended the December 14 wedding of Parker's daughter, who was her childhood friend Eva, to Frank Woods, and stayed for Christmas festivities. The celebrations and activities went on for weeks. In mid-January 1899, Kaʻiulani and a number of other guests mounted horses and rode out for a picnic. What started out as pleasant weather soon turned into a windy rainstorm. While others on the ride donned raincoats, Kaʻiulani was gleefully galloping through the rain without a coat. It was not until later, when they were back on the ranch, that she began feeling ill. Upon learning of her situation on January 24, her father sailed immediately to the island on the steamship "Kinau". Their family physician, "Doctor Walters" (Saint David G. Walters), accompanied him. After medical treatment, the public was told two weeks later that she was on the mend.
