It was my first time riding bicycle in South Korea, and due to time constraint, it had to be a night cycling. As you can see, the cycling path is well defined, well maintained, and well adhered to by both cyclists and pedestrians. The bike path in total (the 4 rivers' cycling path) extends from Incheon to Busan, spanning about 633km, a very attractive destination for cyclo-tourists from around the world, myself included.
