Enjoy a trip to Seoul to the fullest with just one ticket! Seoul's famous, state-of-the-art double-decker bus takes you to the city's attractions. The Yellow Balloon City Bus is an urban circular bus that allows you to get on and off freely at any stop on the route all day long with the purchase of a one-time ticket. It is a 'traditional' bus that departs from Dongdaemun Design Plaza and tours the city center and old palaces such as the Blue House, Namdaemun Market, and Insa-dong. We are operating the 'Culture Course' and the 'Hangang Jamsil Course' that covers the Gangnam area, including Seoul Forest, Jamsil Lotte World Tower, and Olympic Park.
