Cheongnamdae's official admissions page lists individual prices of KRW 6,000 for adults aged 19–64, KRW 4,000 for teenagers 13–18, and KRW 3,000 for children 7–12. Groups of 20 or more pay KRW 5,000, 3,000 and 2,000 respectively. Parking is free.
Registered residents of North Chungcheong, South Chungcheong, Daejeon and Sejong receive KRW 1,000 off with proof of address. Registered residents of Munui-myeon in Cheongju and some eligible veterans or visitors with disabilities may qualify for free admission with documents. The official policy also lists children under seven plus one accompanying guardian, and pregnant people (including up to six months after childbirth) plus one guardian, under its free-admission categories, subject to proof.
A separate discount uses a same-day purchase receipt from a shop in Munui-myeon, allowing up to KRW 2,000 off for one person per KRW 10,000 spent. Group, resident and agreement discounts cannot be stacked; only the most favorable applies. Confirm documents at ticketing. Inquiries: 043-257-5080.
