Haneul Park is the most popular of the five parks situated in World Cup Park which was built to commemorate the 17th FIFA World Cup. Like its name Haneul, which means "sky" in Korean, the park is situated on the highest part of World Cup Park and offers breathtaking views of Seoul. Once a landfill, Haneul Park is an incredible example of ecological and urban regeneration. The annual Silver Grass Festival at Haneul Park is one of the city's most popular events. It is held each October when the silver grass is in bloom. Silver grass is also known as eulalia or pampas grass. The park can be reached by climbing up a wooden stairway that boasts 291 steps or by taking a ride on the park's electric tram.
