a pleasure-hunting monkey.
As a Jakarta resident, I always confused if someone asked me any place she/he can visit to have a scenic view in Jakarta or not too far from Jakarta. But recently I got the answer, a place I visited as a super short escape to refresh my sight and snap some nature photographs.
It is Danau Biru or the Blue Lake in Cisoka, Tangerang regency Banten. Which took around one hour trip from my home in South Jakarta. Nestled on the western outskirts of Jakarta, Danau Biru or Lake Blue offers a short getaway if you want to escape from the crowded capital for a while.
When I mentioned Blue Lake, actually it is not a lake. Danau Biru has not one but three lakes in one area. They are all offer a picturesque natural view that will please your eyes.
I opted to take a train trip and followed by taking the local motorcycle taxi or ojek. I think that was a good decision I made because of the trip we passed through and the stories I got from my ojek driver as a local resident there. The bike went past the breathtaking view of the rice fields and local houses. Indeed, the rice fields is a rare view I can see in Jakarta.
The blue and green lakes
During the journey, my ojek driver also shared a lot of stories about Danau Biru until we finally arrived at the parking lot. As I set my eyes on the blue lake, my mind traveled back to Lake Kaolin in Belitung Island in Sumatra that I visited a couple of years ago, and I think that Danau Biru of Cisoka Village is similar to Lake Kaolin. It turns out they share quite the same background as well.
Lake Kaolin became popular due to its blue color caused by kaolin mining in Belitung Island, while Cisoka’s Danau Biru is caused by the exploitation of sand mining around the area. The local residents said that the sand mining has been abandoned since 2014. Every since then, the site has three basins. Some other I met said the mining activity probably reached several water springs that caused the basins to not only collect water from rain, but also from the ground.
The lake water used to look normal. But two years ago, its surface started to change color, from turbid water that sometimes looked almost green to become really green and then changed again into tosca green.
The first two lakes are located around 100 meters from the parking lot. I can see them directly from the parking lot.
The one on the left has a moss green color and is surrounded by trees that looked more like a small forest.
The lake on the right side is pretty much different with tosca green water, and is surrounded by white rocks and sandy ground. Moving further, I could see the third lake is situated behind the first two lakes. It is also the largest one among them. And like the second lake, the surface is tosca green and the lake is surrounded by white rocks and sandy ground.
The local residents I met around the lakes had no idea why these lakes have different colors despite their location that is pretty close to each other. They are even afraid to taste the water or use it for their daily lives. The simplest explanation is probably because there is a chemical process under the surface or somewhere deep under the bottom of the lakes.
How to get there?
It’s pretty easy because Danau Biru can be easily reached by a train or a car.
