Cheonjiyeon Waterfall
These waterfalls along with the surrounding park and walkways leading up to it provide a decent place to stroll around at night. Even though it's not free. There are a number of bridges and benches along the way, as well as various plant life to add to the mood. Supposedly a certain type of nocturnal eel is found in the pools around the falls, though it's too dark to see anything not actually jumping out of the water. The waterfalls aren't going to overwhelm you by their size (22m high) or power, but on a clear, cool evening in Jeju, the atmosphere is quite pleasant. I can't imagine it would be more interesting in the daytime, especially when you'd be fighting more tourists. Overall it's not exactly what I'd consider a must-see item. For me, I was able to just wind down here from a long day of sightseeing and enjoy the sound of the falls.
