Nari Park.

For those who are visiting South Korea during the summer and want to see beautiful flowers, we recommend coming to Pyeongtaek. It's about a 1-hour ride on the express train from Seoul. You will see fluffy, blooming hydrangeas all over the park. You can't find this atmosphere in Seoul, but you don't have to go far south either. You can come and have a relaxing picnic here. We recommend visiting around June when the flowers are in full bloom.
