Bulgwang Stream (Hanja/Romanization/English: 佛光川/Bulgwang-cheon/The Stream of Enlightened Buddha) is a stream which spans 9.21 km long across three affluent districts in Upper Han River Sector of Seoul: Eunpyeong-gu, Mapo-gu and Seodaemun-gu. Bulgwangcheon is originated at the Precinct of Bulgwang-dong, Seoul Eunpyeong-gu where the temple of Bulgwangsa is located adjacently to the stream. It is a branch river of Hongjecheon (Hongje Stream), one of the branches of Han River.
Bulgwangcheon is previously notable as one of the polluted river in Seoul because there are many garbage floating on the river which produce bad smell. Fortunately, the stream was completely renovated for the 2002 World Cup, and 2007 saw the launch of the Public Art Project, creating dazzling spectacles and street arts along sections of the stream.
With a bike path from Bulgwangcheon, flowing alongside Digital Media City Station in Seoul Mapo-gu, to the Han River, there is good place to take a walk along a riverbank. At the public bike rental stations operated by the Seoul Metropolitan Government, you can rent a bicycle.
