Amsa Prehistoric Village, a quiet outing on the outskirts of Seoul. It has some really nice displays and activities. If history is your thing, this is a must do.
Amsa station (Seoul Subway-Green Line 8) Exit 4.
Walk straight to the Prehistoric Settlement Site
Walking takes about 10 minutes. 15 minutes if you stop to take pictures of the MILLIONS of giant spiders building nests outside the greenhouses on the way to the village. Which I did.
