Myeongdong, the mecca of shopping in Korea, is always bustling with crowds. It can be very difficult to navigate the narrow alleys with heavy shopping bags or large suitcases. Various options exist, including lockers inside Myeongdong Station, nearby department stores, and private storage facilities.
Lockers in Myeongdong Station are extremely competitive. If they are full, consider checking the storage services at nearby Lotte or Shinsegae Department Stores. English and Chinese signage is well-provided for international tourists.
