Everland
Korea's largest theme park is about an hour from Suwon (or about 40 minutes by bus from Seoul Station), but it's worth the detour if you're looking to fill a day with the kids on roller coasters and strolling through the zoo. Highlights include the Thunder Falls water ride; Panda World, where you can spot the cuddly bears; and the sprawling Four Seasons Garden, filled with rows of colorful blooms.
