The lake colors are primarily determined by the pH level and mineral deposits resulting from the former excavation activity.
The site was historically an active sand quarry before being abandoned and subsequently filled by rainwater.
The water is generally considered unsafe for swimming due to varying acidity levels.
The area is occasionally referred to locally as Danau Biru Cigaru.
Telaga Biru Cisoka is an artificial lake system formed from former sand mining excavations in Tangerang, Banten. The site features three distinct pools that undergo color shifts, ranging from blue and turquoise to green, influenced by the acidity levels and mineral content of the water. Visitors can navigate the lakes using rented wooden paddle boats or small raft platforms. The surrounding landscape consists of rugged, man-made cliffs and sandy embankments left behind by industrial activity. The location is an example of land reclamation through ecological succession and tourism development. It serves primarily as a domestic recreational destination for weekend day-trippers. The chemical composition of the water is variable, leading to unpredictable changes in water hue over time.

Bring a hat and sunscreen, as there is very little natural shade around the perimeter of the mining pits.
Wear sturdy, closed-toe footwear suitable for walking on uneven, sandy, and steep terrain.
Carry extra drinking water as facilities are limited in the immediate vicinity of the water's edge.
Do not attempt to hike up unstable sand mounds for photos, as these areas are prone to erosion and collapse.
Avoid swimming in the water; remain on designated walkways and observation platforms.
