Last summer, I got a chance to feel the experience of picnic and ride a bicycle at Han River's area. After almost 5 times, I went to Seoul, Korea; finally I have time to spend at Han River.
It's so wonderful. I don't know how to expressive it, especially when I ride a bicycle after 15 years. Last time I ride a bicycle when I'm 12 years old. Just rental the bicycle at the Bicycle Rental place around Han River and with rate KRW 3,000/hour or KRW 5,000 for 2 hours. For me, I rental it for 2 hours so I don't need have to rush. Just enjoy my day.
One thing, I respect about Korean's culture is after they finish the picnic; they keep all the trash and clean the place. So you can see this park is always clean, even many people were picnicking there even after work. They also allow for picnicking anywhere they like around the Han River Park as long they can keep it clean.
How to go there:
Take off the Yeouinaru Station (line 5) [Exit 2/3]
