The lake was created by damming the Cileunca River during the Dutch colonial period.
The reservoir provides water for the Cikalong hydroelectric power plant.
Nusa Manuk is a dedicated sanctuary for migratory birds that roost on the island in the evenings.
The water depth and temperature are regulated to support local trout and tilapia aquaculture.
Situ Cileunca is a 1,400-hectare artificial lake situated at an elevation of 1,550 meters above sea level in the Pangalengan highlands. Originally constructed between 1919 and 1926, the reservoir functions as a primary water source for the Palayangan River and supports local hydroelectric power generation. The lake is surrounded by productive vegetable farms and extensive tea plantations that define the local agricultural economy. Visitors access the lake's islands, such as Nusa Manuk, via traditional wooden rowing boats. The site is a focal point for regional water-based adventure sports, including whitewater rafting on the outflowing river. Cold mountain air and high humidity are consistent environmental factors due to the geographic location in the Bandung Regency.
The suspension bridge connecting the main banks offers an unobstructed view of the water and the surrounding mountain ranges.
Bring a windbreaker or warm jacket, as temperatures drop significantly once the sun sets.
Rent a local boat guide to reach the private island camping areas for a quieter experience.
Confirm the rafting schedule in advance if planning to engage in water sports, as operations depend on dam discharge levels.
Avoid visiting on weekends and public holidays if seeking tranquility, as local tourism traffic creates significant congestion.
Modest clothing is expected in the surrounding rural villages; littering in the water is strictly prohibited by local community watch groups.
