Ciater Hot Springs is located in Subang Regency on the volcanic slopes of Mount Tangkuban Perahu in West Java, Indonesia, where sulphurous thermal waters with temperatures between 38°C and 43°C emerge from the active caldera geology of one of Java's most visited volcanoes—a landscape shaped by the Sundanese myth of Sangkuriang and the overturned boat that became the mountain. The sulphur-rich mineral composition of Ciater's thermal waters carries properties valued in Indonesian and Sundanese spa tradition for skin conditions, respiratory wellness, and circulatory stimulation, with the waters' distinctive mineral character reflecting the volcanic intensity of the Sunda Arc tectonics driving Indonesia's position as one of the world's most geothermally active nations. Surrounded by tea plantations that carpet the Ciater highland in vivid green terraces—one of Java's most scenic agricultural landscapes rooted in the Dutch colonial era—Ciater Hot Springs offers the unusual combination of volcanic thermal bathing with the visual splendour of Indonesia's highland tea cultivation heritage.
