Korea has arguably the most developed bicycle routes in the world, certainly in Asia, with over 1700+km long bicycle-only roads. Many of those roads go where the rivers flow.
During this Easter holiday break, we decided to check out the part of the bicycle network near Seoul, traveling East along the Han river and up to Bukhang (North Han river) to Nami Island, and then back to the south along Namhangang (South Han River) to Yeoju, before returning to Seoul in 3 days.
