Yangpyeong Tunnel Hopping

Hangang Bike Path
Learn about the converted train tunnels in Yangpyeong County.

The Hangang Bike Path follows a retired rail route in Yangpyeong County (양평군; map) just east of Seoul. The section of the cycling path includes nine retrofitted rail tunnels.

Let’s explore them!


In 2008, rail engineers electrified the trains on the Gyeongui–Jungang Line (경의·중앙선; map), a commuter train on Seoul’s subway network.

These new trains needed overhead wires and gates. In Seoul, where space doesn’t come cheap, engineers needed to remodel the infrastructure around the existing rail line.

The bike path follows a decommissioned railroad route. The newer train tracks and tunnel will run parallel with you.

Outside of Seoul, however, engineers bought up new land, bored tunnels, and laid new rail between Yangsu Station (양수역; map) and Asin Station (아신역; map).

What happened to the old tracks? The Hangang Bike Path.

The bike path’s designers removed the old train tracks and put down a cycling road on its bed. (You can still see bits of the old track along the bike path.)

Designers also retrofitted old features along the rail line like Neungnae Station, Bukhangang Railroad Bridge, and nine train tunnels once used by Gyeongui–Jungang trains.

Art Tunnels

The entrance to an old railroad tunnel converted into a cycling tunnel along the Hangang Bicycle Path in Yangpyeong, South Korea.
Yangpyeong country transformed eight old rail tunnels into cycling and walking paths along the Hangang Bicycle Path.

Most of the tunnels along the rail-line-turned-bike-path measure between 115 to 280-meters. They pass through hillsides in short bursts, cooling cyclists in summer and warming them winter.

However, the second and last tunnel — Yongdam and Gigok — span about half-a-kilometer each. Some proposed that Yangpyeong County transform these underground stretches into bike museums and art spaces. But lack of time and money halted fantastical plans.

Designers instead turned Yongdam and Gigok into “art tunnels” by embedding colorful LEDs and light fixtures into their walls (which may or may not work). 

Asin Gallery (아신갤러리; map), an old Mugunghwa train transformed into an art gallery, hangs out on the east side of Gigok Art Tunnel. Dozens of sculptures and other installations fill up the space between the gallery and tunnel.
