Dieng Plateau Hot Spring

Dieng Plateau Hot Spring is a dramatic geothermal bathing site on the Dieng Plateau in the Wonosobo Regency of Central Java Province, Indonesia — a remarkable high-altitude volcanic caldera at 2,000 meters elevation dotted with ancient 8th-century Hindu temple complexes, multicolored crater lakes, and active fumarole fields that make it one of Java's most extraordinary and otherworldly landscapes. The sulfurous thermal waters emerge at high temperatures from the plateau's active geothermal vents and are part of a long thermal tradition associated with well-being, while the high-altitude setting provides crisp mountain air exceptionally cool by Javanese standards. The combination of Indonesia's oldest surviving Hindu temples, the mysterious Sikidang crater with its bubbling mud pools, and the striking Telaga Warna (Color Lake) make Dieng one of Southeast Asia's most geologically and archaeologically compelling hot spring destinations.
