거문오름
The heart of the UNESCO World Natural Heritage site "Jeju Volcanic Island and Lava Tubes." Its lava tubes come from the parent volcano, and visits require a guided walk with a reservation.
Geomunoreum is the parent volcano of the lava tube system, including Manjanggul. Together with Hallasan and Seongsan Ilchulbong, it is part of the UNESCO World Natural Heritage site. Inside the crater, dense primeval forest grows, and the site preserves vertical shafts, lava channels, and Japanese military tunnels. Visitors must join a guided tour, and the classic crater route takes about 2.5 hours. Reservations must be made in advance on the official website, as daily numbers are limited. The site is closed on Tuesdays. Admission is about 2,000 won. Trekking poles are not allowed, and only drinks may be brought in as food. The site may close in rainy weather.
