Donuimun Museum Village is a great place to visit while you're at the National Meteorological Museum. Though small in scale, it's well-organized and full of interesting exhibits.
There are free exhibition halls to explore, and you can also participate in traditional cultural experiences such as making traditional food, crafting mother-of-pearl keyrings, and learning to play the gayageum (a traditional Korean string instrument). However, you must make a reservation in advance.
Parking can be challenging, but if you visit in the morning, you might find some nearby spots.
