From miners' passages to a visitor attraction
Jade Cave in Chungju, Chungcheongbuk-do, reuses passages from a former mine as an underground visitor site. Rather than seeing it only as a scenic cave, consider that the tunnels were originally built for work, not tourism. That history gives the visit another layer.
Looking for traces of industry
Notice the long tunnels and rock surfaces, and think about how such spaces were once used. Exhibition and experience areas may change, so do not assume every activity is available on every visit. Follow the on-site information and the operator's latest notices.
A November visit begins with the schedule
Chungbuk Tourism's published listing gives April–October hours of 09:30–18:30 and November–March hours of 09:00–18:00, with last admission at 17:00. The address is 26 Mokbeoran-gil, Chungju-si (충청북도 충주시 목벌안길 26), and the listed telephone is 043-848-0503. These are published details, not verified same-day operating status.
Before you go
An underground attraction is different from an ordinary outdoor walk. Follow safety signs and designated paths, and prepare clothing suitable for the ground conditions and cooler environment. Current fees, closures and reservations need separate confirmation. Search '활옥동굴' on Korean map services.
