- It begins in Yongin and flows north to merge with the Dongmakcheon stream in Gumi-dong.
- It then joins the Jungcheon stream in Imae-dong.

Along its entire length, the area is characterized by large apartment complexes that line the banks, creating a seamless integration of residential living and natural scenery.
History and Etymology
The name "Tancheon" carries deep historical roots. The term is written in Hanja (Chinese characters) as 炭川, which literally translates to "charcoal stream." This is believed to be a translation of the native Korean word "Sutnae".
The Connection to Charcoal
The "charcoal" aspect of the name likely refers to a historical area known as Sut-gol or Tan-gol. This region, which corresponds to the modern-day neighborhoods of Taepyeong-dong, Sujin-dong, and Sinheung-dong in Seongnam, was once a significant producer of charcoal. While the stream has been known by various historical names—including Geomcheon, Heomcheon, and Jancheon—its official name was assigned during the Japanese colonial period (1910–1945).
Environmental Evolution
The geography of the area changed significantly following the 1925 flood of the Han River, which altered the merging points of Yangjaecheon and Tancheon. While the water quality faced challenges during the rapid urban development of Seongnam in the 1990s, the stream has seen a gradual improvement in environmental health in the years since.
Recreation and Public Amenities
Today, Tancheon serves as a massive linear park. It is highly popular among locals due to its well-maintained infrastructure designed for health and leisure.
Parks and Sports Facilities
The banks of the stream feature dedicated walking paths and bicycle lanes. To facilitate movement between the two sides, the area is equipped with various vehicle bridges and occasional footbridges. For those looking to stay active, the park includes exercise equipment and sports courts, such as tennis courts.
Summer Fun: Tancheon Water Parks
One of the most popular attractions for families is the series of Tancheon water parks (탄천 물놀이장). Located along the 25-kilometer stretch that passes through Seongnam, these parks are free to the public. They are open annually from July 1 to August 31, between 10 a.m. and 8 p.m. Facilities include changing rooms, chairs, and picnic tables.
