Insider tip — The Cisolok area of West Java near Palabuhanratu on the Indian Ocean coast hosts a remarkable cluster of sulfurous hot springs and geysers fed by volcanic activity along the Sunda arc. The largest spring, Cipanas Cisolok, pulses at near-boiling temperatures before cascading down into bathing pools cooled to around 42°C. The setting amid jungle-covered hillsides and the sound of the ocean a few kilometers away makes this an unusually atmospheric thermal destination. Visit on weekday mornings to avoid the weekend crowds from Bandung and Jakarta.
