Seminole Hot Springs is an unincorporated community in Los Angeles County, California, United States. Seminole Hot Springs is located in the Santa Monica Mountains near Cornell, 3.6miles south-southeast of Agoura Hills at an elevation of .
The settlement began as a resort built around a hot spring. The springs were first identified in 1911, and the spa closed in 1959.[2] As was the case with Radium Sulphur Springs and Bimini Hot Springs elsewhere in Los Angeles County,[3] the waters of Seminole Hot Springs were "discovered" and then commercialized after oil drillers hit water instead of petroleum.[4] Major fires passed through the area in the 1930s and 1940s.[5] The 1941 American Guide to Los Angeles described Seminole Hot Springs as "a year-round health and pleasure resort resort, with springs, cottages, bathhouse, open-air mineral water plunge, and cafe buried in a copse of sycamores below the level of the road."[6]
Now essentially a suburb of the Agoura–Calabasas era, there is a mobile home community at the location. The Woolsey Fire of 2018 destroyed 100 of the 215 mobile homes at Seminole Hot Springs.
