Air Panas Ciater is a celebrated hot spring resort on the cool volcanic slopes of Mount Tangkuban Perahu in Subang Regency, West Java, where sulfurous geothermal waters fill terraced pools surrounded by one of Indonesia's most scenic tea plantations. The site has been developed into a well-organised family resort with multiple pool areas at varying temperatures, making it one of the most accessible and popular thermal destinations on the island of Java. Visitors can combine a soak in the mineral-rich sulfur waters with a stroll through the adjacent Ciater tea estate, sampling freshly brewed highland tea with panoramic views over the steaming pools and forested hillsides.
Insider tip — Air Panas Ciater on the slopes of the Tangkuban Perahu volcano in West Java produces some of Sumatra's most sulfurous hot springs at 43°C, fed by an active caldera just 3 kilometers uphill. Tea plantation terraces surround the pools, giving the setting a deeply Sundanese agricultural character. The combination of volcanic steam rising through tea bushes makes this one of Indonesia's most visually striking hot spring settings.
