Old Caoling Tunnel 舊草嶺隧道

Updated:
Inside the old tunnel. Those are mock railroad tracks you see on the ground.

Old Caoling Tunnel 舊草嶺隧道 was built in the 1920s to connect northern Taiwan with the eastern coast by rail. A new tunnel was built in the 1980s and the old tunnel was closed until 2008 when it reopened as a tourist-friendly bikeway. The main point of entry is Fúlóng 福隆, a beach town in New Taipei City about an hour outside of by train. Riding through the old tunnel makes for a great day trip from —as long as you don’t go on a weekend.

The main drag in Fulong from the railway station exit. Lunch boxes and bicycle rentals are immediately to the left. The way to the tunnel is to the right.

Getting there and getting setup is almost effortless. Take a train to Fulong Station. When you walk out of the station you will see everything you need for a day of riding: lunch box (biàndang 便當) vendors to your left and a convenience store on your right. Stock up on whatever food and drink you need; if you ride the entire loop around the eastern tip of Taiwan you aren’t guaranteed to pass another convenience store for quite some time.

Bicycle rental at Fulong Station.

Bicycle rentals are absurdly cheap—something like 100 to 150 NT for the day (usually until 6 pm). Make sure to get a bicycle that is right for your height—the style in is to ride bicycles that are too small.

Setting out for the old tunnel.

Finding your way to the old tunnel shouldn’t be hard—the roads are marked with signs left and right. Head east (to the right in the photo of the main street above) along a road that parallels the train tracks for a while.

Strange designs on buildings in front of the northern entrance to the old railway tunnel.
Train memorabilia decorates the entire area to the north of the tunnel entrance.

Eventually you will arrive at a small cluster of buildings near the northern entrance to the old tunnel. There are old trains here, steampunk sculptures, more rental shops, and probably a place to get a drink, though I didn’t look closely. (More about that here.)

The mouth of Old Caoling Tunnel.
There are many little nooks along the way.
You can really pick up some speed if you want to; the tunnel is mostly flat and straight.

There is an eerie, cool breeze inside the tunnel. The creepiness is augmented by the sound of music piped over small speakers. Apparently this is an old Taiwanese folk song, diūdiūtóngzǐ 丟丟銅仔. The first two words are onomatopoeia: the sound of water dripping onto a train as it passes through a tunnel.

I have read that the soundtrack used to include the rumble of trains passing by. I didn’t hear any—just the music. Even still, it is one of the stranger aspects of this attraction, particularly since the tunnel was almost empty the day I went.

I’ve never seen this before: a border crossing deep underground.
The gateway to Yilan county. It looks like a prop out of a 1970s science fiction movie.

The old railway tunnel is slightly more than 2 km in length. Partway through one will encounter a surreal sight: the gateway to Yilan county. I had to wait a while for a couple to finish taking a hundred photos of themselves at this curious landmark before I could shoot a few of my own. As a lover of geography I found it quite interesting to conduct a border crossing underground.

The obligatory light-at-the-end-of-the-tunnel shot.
The new railway tunnel is to the left. They run in parallel.
The far side of Old Caoling Tunnel.

The far side of the tunnel exits in Xicheng (usually Romanized as “Sicheng”). There didn’t seem to be much going on here, though I visited on a weekday. Lots of Taiwanese people were milling around in the golden light of a deepening afternoon. I went to explore.

Turtle island from the viewing platform immediately across from the tunnel exit.

The viewing platform across from the tunnel exit affords a good view of the Yilan coastline with Turtle Island off shore. Looking south you can see stretching around to the horizon. It is a beautiful sight, one of the nicest in all .

To return to Fulong you have two choices: return through the tunnel, nice and easy, but I strongly recommend doing the full loop around the easternmost tip of Taiwan.
