JEJU STONE PARK.

Beautiful natural park and museum. We only spent 2-3 hours there but it needs 4-5 hrs to be fair. There is a lot of paths for trailing and unique spots for taking scenic shots. The museum is also great for kids to explore geographical backgrounds of Jeju islands and Korea. It is good to eat something as the cafes have great coffees but not a wide seletion of snacks or food.
