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.

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

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.

Nearby

Bijarim Forest

Two loops split at a crossroads inside the wood. Course A is about 2.2 km of level volcanic-cinder path, 40 minutes to an hour, and takes a pushchair or wheelchair with help on the slopes; course B includes rough stone and does not. Dogs are not admitted, which separates this from most Jeju walks.

Secret Forest

A walk through cedar west of Andol Oreum, with tickets sold from a mint-coloured truck at the entrance. The unpaved loop takes about half an hour and has eight marked spots to photograph, with a stand of hinoki cypress partway round. Closures are posted on the operator's Instagram rather than following a fixed calendar, which is worth checking before driving out here.

Geomunoreum

The volcanic cone that made the caves on this side of the island: lava from here ran about 14 km to the coast and left the Geomunoreum Lava Tube System behind it. In front of the cone a collapse trench runs about 2 km long, 80 to 150 m wide and 15 to 30 m deep, thought to have formed where cave roofs fell in. There are three routes of different lengths, two of which may only be walked with a guide. Eleven departures a day, fifty people each, and booking closes at 17:00 the day before.

Seongsan Ilchulbong Tuff Cone

Two separate walks share the site: a ticketed climb to the summit, 30–40 minutes of stairs, and a free coastal path around Umutgae with a much gentler gradient. The monthly closure is the thing that ruins trips — it is the first Monday, not a holiday pattern anyone guesses.
