Gangwon
Daegeumgul Cave - Daei-ri Cave Area) is a curated attraction in Korea — full details, hours, and access info on the official Korea Tourism page.
Daegeumgul Cave is one of the rare Korean limestone caves accessible only by a small mountain monorail, in the Daei-ri Cave Area of Samcheok, Gangwon. Visitors board a six-minute monorail ride that climbs through pine forest to the cave entrance, then walk a roughly forty-minute lighted route past underground waterfalls, an emerald cave lake, and elaborate flowstone formations. Numbers are tightly capped per session, which keeps the experience uncrowded and the cave atmosphere genuine. Reservations are essential and often sold out two weeks ahead in summer. Pair with the larger Hwanseongul Cave nearby and a coastal lunch in Samcheok for a full day on the East Coast.
