What to skip in heavy rain
Large outdoor parks (Seoul Forest lawns, Oil Tank Culture Park outdoor zones) offer little shelter. Children's Grand Park has indoor corners but is mainly outdoor.
Practical notes
- Carry a compact umbrella — sidewalk crowds spike when it rains.
- Subway entrances get slippery; allow extra time.
- Verify attractions are open — some close during typhoon warnings.
FAQ

- What indoor options work for toddlers?
- Aquariums, children's museums, and mall play zones with short visit windows. Avoid over-scheduling.
- How is stroller use on rainy days?
- Wet subway floors and crowded entrances are the main challenges. A foldable stroller and elevator-planned route usually help.
