But before you visit, there are a few rules and local guidelines you should know. Some activities that may seem harmless can disturb the environment, create safety problems, or be restricted along the stream.

Here are 9 things you should not do at Cheonggyecheon Stream — and a few simple tips to help you enjoy your visit responsibly.

1. Do Not Fish or Catch Fish

Fishing or catching fish is not allowed at Cheonggyecheon Stream.

Cheonggyecheon is more than just a popular walking area. It is also an urban stream where fish and other aquatic species live.

Even if you see fish in the water, please enjoy watching them rather than trying to catch them. Protecting the stream’s ecosystem helps keep Cheonggyecheon enjoyable for everyone.

2. Do Not Enter the Water

Visitors should not enter or walk in the stream.

Even when the water looks shallow and calm, entering the stream can be unsafe and may disturb the aquatic environment.

Stay on the designated walking paths and stepping stones, and enjoy Cheonggyecheon from the areas provided for visitors.

3. Do Not Throw Trash into the Stream

Do not throw trash, food, or other waste into Cheonggyecheon Stream.

Litter can pollute the water and harm fish and other wildlife living in and around the stream.

Use designated trash bins when available, or take your trash with you until you find a proper place to dispose of it.

4. Do Not Feed the Fish or Wildlife

Avoid feeding fish, birds, or other animals around Cheonggyecheon Stream.

Human food may not be suitable for wildlife, and regular feeding can change their natural behavior and affect the stream’s ecosystem.

The best way to enjoy the wildlife at Cheonggyecheon is simply to observe it without feeding or disturbing it.

5. Do Not Ride Bicycles or Electric Scooters on the Walking Path

Avoid riding bicycles or electric scooters along the narrow pedestrian paths beside Cheonggyecheon Stream.

These paths can become crowded, especially on weekends and during busy hours, so riding can create safety risks for pedestrians.

Walk your bicycle when necessary and use designated roads or cycling routes instead.

6. Do Not Smoke Along the Stream

Avoid smoking while walking or relaxing around Cheonggyecheon Stream.

The area is used by many pedestrians, families, and visitors, and smoking can make the experience uncomfortable for others.

If you need to smoke, use a designated smoking area away from the stream and pedestrian paths.

7. Do Not Damage Plants or the Surrounding Environment

Do not pick flowers, break branches, or damage plants around Cheonggyecheon Stream.

The greenery along the stream is part of the restored urban environment and helps create a pleasant habitat for both wildlife and visitors.

Enjoy the scenery, take photos, and leave the plants as you found them.

8. Do Not Make Excessive Noise

Cheonggyecheon is a popular place for walking, resting, and enjoying a peaceful break in the middle of Seoul.

Avoid playing loud music, shouting, or creating excessive noise that may disturb other visitors.

Keeping the volume down helps everyone enjoy the relaxing atmosphere of the stream.

9. Do Not Ignore Safety Signs or Restricted Areas

Pay attention to safety signs, barriers, and restricted areas along Cheonggyecheon Stream.

Access to some sections may be temporarily restricted because of heavy rain, maintenance, or other safety concerns.

Always follow posted instructions and use the designated paths to enjoy your visit safely.
