Regardless of the season, we recommend bringing a small backpack for day trips, an adapter for Korean power outlets (type F), and a portable charger. Given the number of rainy days even outside the peak rainy season, a compact umbrella may come in handy at any time of year. Do not forget a personal first aid kit with necessary medications as well.
