5.16 Tree Tunnel

Overview The 5.16 Road is the first national highway of Jeju and connects the cities of Jeju and Seogwipo. Drive the winding road toward Seogwipo to the points about 2.6 to 1.2 kilometers at a distance from Hallasan Seongpanak Rest Area to reach a tree tunnel shaped like an arch made with evergreen trees and deciduous trees. At the northern entrance to the tree tunnel, there is a sign reading, “The road is more beautiful if you drive slowly.” The road here is narrow and has many curves, causing a risk of accidents, so drivers should be careful. Another reason to slow down while driving on this road is to appreciate the surrounding scenery. Located at the foot of Hallasan Mountain, the road provides various aspects of nature throughout the four seasons. Trees that extend out from both sides of the road and are bent as if embracing the sky provide cool shade in the summer, red leaves in the fall, and dazzling snow scenes in the winter. The 5.16 Tree Tunnel presents picturesque four seasons of Jeju.
