Oasis in Seoul: What's happening at the restored Cheonggyecheon stream

Cheonggyecheon is one of Seoul's most iconic urban streams that becomes a nice rest area especially during the hot summertime.

But it wasn't this welcoming or comforting 20 years ago.

Park Kun-woo tells us more.

With daytime temperatures soaring past 30 degrees Celcius, people in Seoul are doing all they can to stay cool -from carrying sun umbrellas to clutching icy drinks.

And for many, it's the perfect weather to enjoy the water, or even get right in.

And there's a special place that's drawing big crowds -the upper part of Cheonggyecheon, temporarily opened to the public to celebrate the 20th anniversary of the stream's restoration.

Laughter echoed as children and adults splashed, kicked up water, and even waded through stronger currents for fun.

International tourists were also spotted easily, cooling off and snapping photos.

"Living in somewhat of a big city you don't normally get to see really lovely streams like this especially when it's so hot and humid. Kind of refreshing to be able to step in the water. It was a lot of fun."

But for Seoulites, Cheonggyecheon isn't just for play, it also offers a peaceful escape from the heat.

"It's been so hot lately, but by the stream, it feels cool, so it's a great place to rest. I often like coming out here for some fresh air especially as sitting all day at work feels stuffy."

That comfort is the result of a remarkable transformation that began two decades ago.

"Cheonggyecheon was once hidden under concrete during Korea's industrial boom. Restoring it raised environmental concerns -but now it's clean enough for native fish and birds to thrive. A true case of urban ecological revival."

In fact, the stream is home to around 20 native fish species, including the Korean spotted barbel, which only survives in grade-two or cleaner water.

And that's thanks to regular water and bacteria tests conducted to maintain quality.

Beyond ecosystem revival, the stream is widely recognized as a successful model of urban water management, offering more than just eco-friendly value.

"Cheonggyecheon helps lower the surrounding temperatures raised by heat-absorbing pavement like asphalt, and even improves air quality, acting like an air conditioner for the city."

Seoul now plans to transform more than 300 kilometers of streams, running through the city, into vibrant, accessible waterfront parks just like Cheonggyecheon.

And as the city moves toward a more water-sensitive future, Cheonggyecheon stands as a reminder that even in the heart of a big city, nature can make a peaceful comeback.
