Hyangga Tunnel was constructed in 1931 under Japanese colonial rule to facilitate the transport of Honam region agricultural resources.
The tunnel spans roughly 384 meters through rock formations adjacent to the Seomjin River.
Bullet impacts from the Korean War are still embedded in the interior brickwork, preserving wartime history.
It was part of the original narrow-gauge railway line before the rail route was relocated in the 1960s.
The abandoned railway tunnel has been transformed into a modern cycling and walking trail equipped with LED lighting.
The adjacent Hyangga Bridge was constructed as a suspension bridge in 1928, predating the completion of the tunnel.
The site connects directly to the popular multi-kilometer Seomjin River bicycle path network.
Hyangga Tunnel is a historical railway tunnel located in Daega-ri, Pungsan-myeon, Sunchang-gun, Jeonbuk State, South Korea. Originally built during the Japanese colonial period in 1931 as part of the Jeolla Line railway, it has been repurposed into a pedestrian and bicycle path. The tunnel measures approximately 384 meters in length and cuts through a rocky hillside alongside the Seomjin River. During its construction, forced labor was utilized, leaving a poignant historical footprint on the structure. Bullet marks from the Korean War remain visible on its brick walls, serving as a silent witness to past conflict. Today, it forms a key segment of the Seomjin River Bicycle Path, connecting cyclists and walkers to nearby scenic attractions. The interior features colorful LED lighting and art installations that illuminate the dark passageway. Visitors can enjoy sweeping views of the surrounding river landscape and the historic Hyangga Wooden Bridge near the tunnel exits.

Combine your visit with a walk or bike ride across the nearby Hyangga Bridge for panoramic river views.
Wear comfortable walking shoes if exploring the unpaved paths surrounding the tunnel exits.
Do not walk in the middle of the path without checking for oncoming bicycles, as the tunnel is shared by pedestrians and cyclists. Avoid touching or attempting to chip away at the historical bullet marks on the brick walls.
