If you want to hit most of Seoul's major attractions but aren't keen on traversing the city by taxi or subway, these buses are the way to go. For a mere $10, you can hop on and off at at least two palaces, the major markets and N Seoul Tower, a communication tower that rises 479.7 m (1,574 ft.) above sea level and has a revolving restaurant and good views of the city — and get free history lessons en route. Look for the blue sign poles around the city to board. Double- and single-decker buses run Tuesday through Sunday from 9 a.m. to 7 p.m. There is also a night run from 8 p.m. to 10 p.m. Buy tickets on board.
