Telaga Biru Cisoka

Telaga Biru Cisoka is an artificial lake located in Cisoka District, Tangerang Regency, Banten, Indonesia. Formed from a former sand and clay excavation pit that filled with rainwater, it is known for its striking turquoise-blue water. Surrounded by white limestone cliffs and sparse vegetation, the lake has become a popular local photography and sightseeing spot. Despite its scenic appearance, the water is not suitable for swimming due to depth and former mining conditions.

Visitors can expect a former mining pit transformed into a lake with bright blue-green water contrasted against pale limestone cliffs and earth embankments. The area is open with limited shade and simple paths around the perimeter. Visitors can walk along the banks, view the lake from several elevated points, take photographs, and rest at small stalls. There are no boating facilities and swimming is not permitted. The setting is rustic and minimally developed.

The lake originated as a sand and clay quarry in Cisoka. After mining activities ceased, the excavation pit was left abandoned and gradually filled with rainwater over time, forming an artificial lake. The depth and mineral composition of the water produce its characteristic blue color.
