Wika Hot Spring, in Bogor, West Java, is an iron-rich hot spring with water reaching around 40°C. An open-air pool allows wild bathing here, surrounded by green hills.
Insider tip — Wika Hot Spring is located in the greater Bogor area of West Java, on the slopes of the volcanic highlands south of Jakarta. The iron-rich waters emerge from the geothermal system associated with the chain of active volcanoes that define Java's interior, including the nearby Gunung Salak and Gunung Pangrango. The lush rainforest setting and the cool highland air at around 500 metres elevation offer a refreshing counterpoint to the warm mineral pools.
