Seoul mixes flat, easily walkable districts like Myeongdong and Gangnam with hillier, more traditional neighbourhoods such as Bukchon Hanok Village, where narrow, sloped lanes wind between traditional houses. The contrast between old and new is part of what makes walking here so engaging, sometimes within the same short stretch of street.
The Cheonggyecheon stream, a restored waterway running through the heart of downtown, gives walkers a sunken, mostly flat path that cuts calmly beneath the busy streets above, a favourite escape from traffic noise without leaving the city centre.
Seoul's scale is considerable, so covering more than one or two districts in a single day on foot alone is ambitious. Combining focused walking within a neighbourhood with subway hops between them tends to work better than trying to walk the whole distance.
