Underground Forest
谷底林海
A primeval conifer forest in a volcanic collapse valley on the north slope, where Korean pine, spruce and fir shade the trail. A wooden boardwalk runs through it, making it the best north slope forest for a stroll.
The Underground Forest, also called the Valley Sea Forest, lies near the north slope park gate. It is a huge collapse valley formed by volcanic activity, where Korean pines, fish-scale spruces and firs more than a century old grow. The ground is covered with moss and ferns, and it is cool and damp. A boardwalk loop of about 2 km takes you past fallen trees, tree hollows and clear streams. The whole walk takes about 1–1.5 hours. The Underground Forest is included in the north slope ticket. It is one of the eco-shuttle stops on the north slope and is usually scheduled after Heavenly Lake and the waterfalls. Mosquitoes are common in the forest, so wear long sleeves.
