Why the slope looks different at Dokkaebi Road
Mysterious Road is known for an optical illusion that makes an actual downhill slope look uphill. Read the explanation of how the surrounding terrain affects your view, and distinguish this from gravity acting in reverse.
Compare the slope underfoot with the terrain in the distance. Dokkaebi Road is another name for the same place; do not interpret it as proof of a supernatural effect.
Use designated viewing areas instead of experimenting on the road
The suggested 15–30 minutes is an editorial estimate for reading the information and observing from public pedestrian areas. Check current road traffic and visitor routes, and follow guidance for designated parking locations.
Do not copy vehicle experiments from older descriptions by putting a car in neutral or rolling objects onto the road. This is a real road, so take photos and observe only within areas where traffic controls and on-site supervision have been confirmed.
Discuss optical illusions with children without crossing the road
With children, discuss why the slope you see may differ from actual measurements. You can understand the principle through the information provided without needing to carry out an experiment to enjoy the site.
Do not stand in the roadway to photograph vehicles or cross without authorization. Prioritize children’s movements, and do not enter sections restricted by on-site management.
