There are so many different waterfalls for you to visit along Jeju Island's southern coastline and Cheonjiyeon Falls isprobably the best of the lot. It isn't just one waterfall but a series of three that you can explore by foot. There's plenty of parking at the top, with the pathway taking you down the steep wall carved by volcanic activity thousands of years ago, to the stream, and first waterfall, below. From there you make your way downstream enjoying the other waterfalls and fantastic scenery along the way. You could easily spend a few hours here, but do note that some mobility will be required to get down and back up from the stream.
