One of the three god’s mountains

I headed to Mara Provincial Marine Park to circuit the coastline. This was only a three kilometre trail running along the high cliffs above the East China Sea. I hoped for a better view of its highest point.

Manjanggul Lava Tube

There were about 160 lava tubes on Jeju Island. Manjanggul Lava Tube was the biggest at over seven kilometres in length. It was formed between 1 000 to 3 000 years ago when Geomunoreum volcanic crater erupted. Near Manjanggul, four other lava tube caves were formed, but only Manjanggul was open to the public.
