It is identified as the 'Titik Nol' or Point Zero of the 297-kilometer-long Citarum River.
The lake is fed by seven distinct natural springs that converge to form the river's headwaters.
The water basin is strategically vital for the irrigation of agricultural lands in the Bandung basin.
The elevation of the site is approximately 1,500 meters above sea level, contributing to a cold microclimate.
The location serves as the border intersection for three mountainous peaks: Wayang, Windu, and Malabar.
Situ Cisanti is the officially recognized Kilometre Zero point of the Citarum River, the longest and most significant waterway in West Java. The site functions as a lake basin fed by seven primary springs, including Pangsang, Cisanti, Cisadane, Cikolebere, Cikahuripan, Cihaniwung, and Citarum. It is situated at the base of Mount Wayang, Mount Windu, and Mount Malabar within a mountainous catchment area. The surrounding landscape consists of managed pine forests and tea plantations that protect the watershed's integrity. The lake serves as a critical hydrological reserve for the Bandung Regency and the wider West Java province. Recent ecological restoration efforts have focused on maintaining water quality and preventing sedimentation. The perimeter of the lake features a pathway allowing for a full circuit of the water body. The environment is characterized by cool, high-altitude temperatures throughout the year.
The wooden jetty and the designated 'Kilometre Zero' monument marker located at the edge of the lake.
Wear layered clothing, as the high-altitude temperature drops significantly once the sun sets.
Bring waterproof footwear if you plan to walk the perimeter trail during the rainy season.
Carry out all personal trash to respect the site's role as a protected water catchment area.
Do not visit during the peak of the rainy season, as the access roads become prone to mud and visibility is frequently obscured by thick mist.
Maintain silence near the spring areas, avoid swimming or polluting the water, and wear modest clothing suitable for rural Indonesian mountain communities.
