The Koreans we were traveling with said that this was the largest folk village they had ever been to. It is very large, with many many huts, buildings and gardening examples. Sunscreen and good walking shoes are a must. This is not a quick in/out place. There are several restaurants inside. There is a Jeju cactus fruit taffy shop inside that will give you free samples - so yummy we had to buy a few bags to bring home!
This is also a popular tourist destination, but the place is so big that it never felt overcrowded anywhere we were except the entrance. There are waterfalls, a maze, flower gardens, and many little shops tucked in here and there all over the place. There are restrooms near the main entrance.
If you want to experience an almost overwhelmingly large example of Korean folk history, this is your place!
