Manjanggul Lava Tube

만장굴

A lava tube about 7.4 km long whose main passage runs 18 m wide and 23 m high. Roof collapses left three entrances; visitors may use only the second, and may walk 1 km in from it. At the end of that kilometre stands a lava column about 7.6 m high, said to be the largest known anywhere, and that column is also where you turn round. The operator files this cave as partly open — the other caves inscribed with it are closed to the public altogether.

Language

The lava column at the end of the open section of Manjanggul, lit in the dark and rising from floor to ceiling.

Place information

Korean name: 만장굴
Opening hours: World Heritage guide service 09:00–16:00
Closed: 1st Wed of the month
Hours notes: The operator's page carries a closing day, a fare table and the car park but no opening or closing time. The nearest thing to hours is the guide service: 09:00 to 16:00, meeting at the ticket office, one hour, free, and signed up for on the spot. The walk is an out-and-back — the open section is 1 km one way, so you return by the way you came. The operator lists a torch and trainers as things to bring, and a raincoat and a warm layer in wet weather.
Time needed: 1 hour
Admission: ₩4,000
Length: 7,400 m · The length of the whole cave, not of the walk: the operator allows 1 km in from the second entrance. The main passage is 18 m wide and 23 m high, which is two figures rather than one, so neither is carried here.
Operated by: Jeju World Heritage Office

Stories about this place

Four places on Jeju's east side, and who decides how far in you get
Manjanggul is 7.4 km long and 1 km of it is open; Geomunoreum has three routes and you pick one when you book; the Secret Forest is a loop a landowner opened; and at Seopjikoji nobody has set an extent at all. All four are places you park and walk into — what differs is who decides how far you walk.
One day on Jeju's east side, timed by the operator rather than by me
Geomunoreum, Manjanggul, Bijarim and Seongsan Ilchulbong all have a published duration — and all four are on the same page. So this route has no start times and a stay length at each stop instead. One thing is fixed: Geomunoreum's booking closes at 17:00 the day before.
