Boyes Hot Springs

Boyes Hot Springs (also called Boyes Springs or The Springs[5])is a census-designated place (CDP) in Sonoma Valley, Sonoma County, California, United States. The population was 6,656 people at the 2010 census. Resorts in Boyes Hot Springs, El Verano, Fetters Hot Springs, and Agua Caliente were popular health retreats for tourists from San Francisco and points beyond until the middle of the 20th century because of the geothermic hot springs that still well up from deep within the earth.

The area was first occupied by Indigenous peoples who discovered and used the hot springs that the area is named after. Eventually, in July 1840, Lazaro Piña was deeded 50,000 acres by the Mexican government as Rancho Agua Caliente. Sometime in 1849 Thaddeus M. Leavenworth acquired 320 acres of the Rancho in what became present-day Agua Caliente, Fetters Hot Springs, Boyes Hot Springs, and part of Maxwell Farm.[6] In 1889, property was being sold in the area as being near the “celebrated old Indian Medicine Spring.”[5] Henry Ernest Boyes discovered hot springs in 1895 in the central part of the area. He and his wife called the area Agua Rica.[5][7] and started the Boyes Hot Springs Hotel, which is now the site of the Fairmont Hotels and Resorts’ Sonoma Mission Inn and Spa.[7] The area became popular with tourists, with over 70,000 visiting each year. A railroad serviced the area during this period.[8]
