One our favorite spots along the Cheonggyecheon this time of year is hidden beneath Gwanggyo Bridge where you can enjoy ‘Cheonggye Soul Ocean,’ a special media art exhibition that uses six projectors to display gorgeous visuals across 40 meters of the water’s surface. From whales swimming between your feet to Monet’s floral masterpieces floating down the stream, it’s an incredibly soothing way to unwind, especially after a long busy day or week.
