The water source is geologically linked to the vast karst formations of the Tuban limestone mountains.
The spring provides a consistent year-round water supply for rice fields in the downstream villages.
The site sits near the border transition between Montong and Singgahan sub-districts.
The water clarity is maintained by the natural filtration process through porous limestone layers.
Sumber Mata Air Krawak is a natural spring located in the Guwoterus forest area of Tuban, East Java. The site features a crystalline turquoise pool fed by underground aquifers, surrounded by dense tropical karst vegetation. The water flows from the limestone hills, creating a constant stream that feeds into the local irrigation system. It serves as a local recreational spot known for its clear, cool water and relatively remote forest setting. The spring acts as a primary water source for nearby agricultural land in the Montong and Singgahan districts. The basin is characterized by rocky terrain and shaded bank areas under mature canopy trees.

Bring water shoes to navigate the rocky and potentially slippery limestone floor of the spring.
Store electronics in waterproof bags, as the surrounding area is humid and near the water's edge.
Visit during the dry season for the clearest turquoise water, as runoff during rain can cloud the spring.
Avoid visiting during heavy rainfall as the muddy terrain surrounding the spring can become extremely slick and difficult to access.
Respect local customs by wearing modest swimwear; refrain from using soap or chemical detergents in the pool to protect the ecosystem.
