Yeouido E-Land Cruise operates sightseeing boats on the Han River from Yeouido, showing the river at night and views across Seoul. Cruises run by time of day, including daytime, sunset, starlight and moonlight departures, with live performances and a seagull feeding experience on board. Passengers must bring ID and fill out a boarding report at the ticket office 30 minutes before departure to receive a ticket. Early May evenings are still chilly, so bring an outer layer.
