Haneul Park is part of World Cup Park. It was created to restore the ecological environment and operates its facilities using natural energy. It consists of eulalia fields, mixed grasslands, a rock garden, sunflower fields, an observatory and rest area, and wind turbines. Among the World Cup Parks, it is the closest to the sky and showcases the transformation from a barren landfill to a restored natural environment. In autumn, the silver eulalia flowers create a spectacular sight, offering panoramic views of Seoul, including Bukhansan Mountain and the Han River. It is also known as a famous spot for beautiful sunsets and night views.
