The night tour at Gyeongbokgung is open every year in the spring from early May to early June, and in the fall from late September to late October.

The entrance fee for the night tour is 3,000 won and usually requires advance booking, however, for foreign visitors, you can simply present your passport at the ticket counter to purchase tickets on the day of your visit without a reservation.

Please note that Gyeongbokgung limits the number of foreign visitors to 300 per day. To ensure you can secure tickets, it's highly recommended to arrive at the palace early.
