Brief history
Before the arrival of the European settlers in the region the area was home to the Tonto Apache tribe. They were the first to enjoy the natural hot spring waters which flowed in the area. Around 1748 and 1750, the Spanish missionaries arrived in the area and called it Agua Caliente which is Spanish for "hot water". Arizona belonged to Mexico until the end of the Mexican–American War in 1848. The Treaty of Guadalupe Hidalgo and the 1853 Gadsden Purchase clearly defined the U.S–Mexican boundaries.

In 1858, a stagecoach station of the Butterfield Overland Mail was established in the "Flap-Jack Ranch". It was located six miles from the Agua Caliente hot springs along the Gila River, 84 miles from Fort Yuma.

King S. Woolsey, an American pioneer rancher, Indian-fighter, prospector and politician in 19th century Arizona owned a ranch where the hot spring waters were located. On one occasion John Ross Browne and Charles Debrille Poston a.k.a. "Father of Arizona", due to his efforts lobbying for creation of the territory, visited and stayed in Woolsey's ranch. According to John Ross Browne: "We had a glorious bath in the springs next morning." By 1873, word had spread about the hot springs and many visitors, which included miners and cowboys went there.

In 1897, a 22-room resort was built where Woolsey once had his ranch. It was named the "Agua Caliente Hotel". Arizona's first elected governor George W. P. Hunt was among those who visited and stayed in the hotel in the late 1800s. Various stone houses were built in the area, which included a store, saloon and residences. Plus, the small town also had a cemetery.

Decline of Agua Caliente
The over-irrigation of the farms and ranches nearby may have been one of the causes for which the water of the springs dried up. During World War II, a swimming pool was built for the use of the officers of nearby Camp Horn. However, once the war was over and the Arizona State Highways 85 and I-8 were built and bypassed Agua Caliente, the town was deserted and eventually became a ghost town.
