The hot spring water originates from the volcanic activity of Mount Tangkuban Perahu, which is located in close proximity.
The water is rich in sulfur, which is traditionally associated with skin treatment and therapeutic benefits for rheumatic conditions.
The site was established in a valley that allows for a natural gravity-fed flow of thermal water from the mountain sources.
The resort area covers over 30 hectares, incorporating both natural streams and constructed swimming pools.
The temperature of the water is naturally maintained by volcanic geothermal energy before it reaches the bathing basins.
Sari Ater Hot Springs is a thermal bathing complex located on the slopes of the Tangkuban Perahu volcano in West Java. The resort utilizes naturally heated mineral water derived from the crater of the volcano, piped into various pools across the grounds. The water temperature in the main pools typically ranges between 35 and 45 degrees Celsius. The facility includes a mix of public open-air bathing areas, private pool rooms, and modern resort accommodations. Visitors can access multiple pools with varying depths and temperatures, some of which are designed for families and children. The landscape is dominated by dense forest, tea plantations, and rolling hills characteristic of the Subang highland climate. Water is diverted from the active volcanic source, resulting in a distinct sulfurous mineral content. The site is part of a larger recreational park that offers additional activities such as mini-golf, outbound training, and horseback riding. It serves as a major wellness destination for locals from the nearby Bandung area seeking the therapeutic properties of volcanic water.

Bring a change of clothes and a high-quality towel, as humidity remains high in the valley.
Use the private pool rooms if you prefer a quieter, more personal bathing experience compared to the public open-air pools.
Wear non-slip footwear, as the stone pathways near the hot spring outlets can become slick.
Avoid wearing silver jewelry in the water, as the high sulfur content will cause it to tarnish and darken almost instantly.
Open daily throughout the year; peak attendance occurs during national holidays and Indonesian school breaks.
Modest swimwear is expected in public areas; communal showering is required before entering the pools.
