Tongri Tantan Park at 116-44 Tonggol-gil, Taebaek uses former mining tunnels for digital experiences, including augmented-reality photo spots and media-art sections. A Korea Tourism Organization page updated October 7, 2026 lists opening hours as 09:10–17:00 and Mondays as closure days, shifted to the next weekday if Monday is a public holiday.

Accessible parking for three vehicles, step-free entry, an elevator and loans of wheelchairs and strollers are listed. These amenities do not establish that every tunnel attraction is wheelchair-accessible.

Check the routes inside individual tunnels, scheduled experience sessions and temporary maintenance closures with the operator before the visit.
