This 8.4 km stream is proof that renovations can change the public perception of something completely. The stream used to be polluted and looked like a huge trash pile, so the authorities decided to have it covered with a highway in 1979. In 2003, they decided to restore the stream as a form of eco-friendly promotion regarding urban development.
The project was bashed by the public in the beginning, but after it was done, this place became a popular spot for relaxing and enjoying nature. The water was purified and became a natural habitat for various species of fish, insects and birds. It also helped with cooling down the surrounding areas by around 3.5°C, and the stream acts as prevention from floods during heavy rains.
There are numerous festivals during which the water and the paths along the stream light up and provide a romantic atmosphere for locals and tourists alike.
It is highly recommended to visit this place during summer because the cold breeze is a nice surprise after walking in the concrete jungle for several hours. Bring some snacks, a good book and immerse yourself with the locals.
