Glen Ivy Hot Springs California

Glen Ivy Hot Springs is a historic hot spring resort in Corona in Riverside County, California — known affectionately as 'Club Mud' for its famous red clay pool where visitors cover themselves entirely in mineral-rich clay and dry in the California sun. The chloride and silica-rich thermal spring waters, drawn from deep aquifer formations beneath the Santa Ana Mountains, feed a comprehensive collection of outdoor pools maintained at a range of temperatures, offering everything from hot mineral soaks and a sulphur pool to cool freshwater lagoons in a subtropical garden setting of bougainvillea and palm trees. The resort traces its thermal bathing history to 1860 when a hotel was established to serve visitors making a journey from Los Angeles to 'take the waters', making it one of California's oldest continuously operating hot spring resorts. Glen Ivy's proximity to greater Los Angeles — approximately 70 kilometres southeast of the city — has made it Southern California's most popular day spa destination for over a century, combining accessible natural mineral spring bathing with the quintessentially Californian outdoor resort experience.
