What is Cheonggyecheon?
It is an 11-kilometer-long stream running east to west through central Seoul. Once a neglected and covered waterway, it was dramatically restored in 2005 and has since become one of Seoul’s most beloved urban parks. The stream starts near Gwanghwamun and flows through several districts before joining the Jungnangcheon and eventually the Han River. Today, it is a lush, accessible green corridor, attracting millions of visitors each year for walking, relaxation, and cultural events.
Why Cheonggyecheon is Special
-
Urban Renewal Success Story: Its restoration is a global model for urban regeneration, transforming a polluted, concrete-covered stream into a thriving ecosystem and public space.
-
Ecological Haven: The stream supports diverse wildlife, including fish, birds, and insects, and is lined with native plants, making it a living classroom for ecology enthusiasts.
-
Cultural Hotspot: It hosts festivals, art installations, and night markets, making it a vibrant center for community life in Seoul.
-
Accessible Escape: With well-maintained walking paths, bridges, and seating areas, Cheonggyecheon is a favorite spot for joggers, families, and tourists seeking a peaceful escape from city life.
2025 Cheonggyecheon Summer Attraction Project: What’s New?
This summer, Cheonggyecheon is more magical than ever. The project brings together art, nature, and sustainability with a series of innovative installations and events designed to help citizens and visitors beat the heat and experience the stream in a whole new light.
1. Giant Designer Shade Canopy
From July 11, a spectacular 50-meter-long designer shade canopy covers the stretch between Mojeon Bridge and Gwangtong Bridge. This installation provides a cool, shaded retreat from the summer sun, making it the perfect spot to relax during the day. What’s more, the canopy is a collaboration between the Seoul Facilities Corporation and Volkswagen Group’s local foundation, Cheonggye Atti. After the project ends in September, the canopy fabric will be upcycled into stylish bags and pouches, which will be distributed to citizens in community sharing events. This initiative not only offers comfort but also promotes sustainability and creative reuse.
2. Firefly Nightscape: Illuminating the Stream
As night falls, Cheonggyecheon transforms into a wonderland with its firefly-inspired nightscape lighting. Solar-powered lights are installed along the riverside greenway between Mojeon Bridge and Gwangtong Bridge, creating the enchanting effect of fireflies flickering among the foliage. These lights operate from 9 p.m. to 5 a.m. (subject to seasonal changes), offering a magical backdrop for evening strolls, romantic dates, or family outings. The gentle glow of the firefly lights adds a touch of fantasy to the city’s nightscape, making the stream a must-visit Seoul destination after dark.
3. Firefly Citizen Experience: See Real Fireflies in Seoul
Nature lovers and families will be thrilled by the Firefly Citizen Experience, held from July 21 to 23. During these three nights, from 9 p.m. to midnight, everyone is welcome to visit the ecological pond near Majang 2 Bridge and the Cheonggyecheon Ecology School. Here, you can observe real fireflies in their natural habitat—a rare and magical sight in the middle of a bustling metropolis. This special event is made possible with guidance from the Muju Firefly Research Institute, ensuring a safe and educational experience for all ages.
A Model of Urban Ecology
The restoration and ongoing care of Cheonggyecheon have turned it into a thriving urban ecosystem. Recent joint research with the National Science Museum revealed the presence of shiri, a freshwater fish that only inhabits clean water, throughout the stream. This discovery is a testament to the stream’s successful ecological restoration and its role as a haven for biodiversity in Seoul. From dragonflies and birds to native plants and fish, it is now a living symbol of the city’s commitment to sustainability and environmental stewardship.
