I was a bit sceptical about this trip - I thought it would be very 'disney' but I thoroughly enjoyed it and am glad I went!
It is exactly what it says it is - a reconstruction of an old Korean Village and it is VERY well done. You can see potters and carpenters at work (and of course buy their wares if you wish). The buildings are very well done - from the peasant's cottage up to the judge's grand house and jail.
There are also folk dances, see-saw displays and tight rope walking shows to watch.
I went on an organized tour with an English speaking guide (City Tours: Brenda)but you can do it independently if you wish.
It's located about 40km outside Seoul.
