Jiugong Tunnels (aka Siwei Tunnels 思維坑道) are the most impressive tunnels on Little Kinmen, and extremely similar to the Zhaishan Tunnels on Kinmen Island. Originally built to protect ROC ships from bombing raids, the tunnels actually go through the island, connecting the ocean from each side.
Jiugong Tunnels were completed in 1965 to protect ships, connecting Jiugong Pier to Luocu Fishing Harbor. The tunnel connects these by going under a hill on the south side of Little Kinmen. The tunnels are 790 meters long and 11.5 meters high, feature 5 underground piers, 4 exits to the sea, and in its prime it could fit up to 52 ships in the tunnels.
Hours: 8 AM to 5 PM every day
There are many tours and activities available on the islands, such as fishing, clamming, traditional Chinese Costume Experience, Water Gun Shooting, Night Otter Spotting, SUPing / Paddle Boarding, Intertidal Eco Tour, Handmade Metalworking DIY, and many others. For more information, look at other tour/ferry sites or book a personalized tour with Klook here or KKday here.

The Jiugong tunnels were our last stop on our trip to Little Kinmen. You can see their opening before you even walk inside. Its sad though that the entrance to the tunnels have been filled in with rocks.
At the entrance to the tunnels, there are exhibits explaining the geology and history of the tunnels.
Helmets are also available if you feel like taking safety seriously.
The entrance to the tunnels looking from the inside. It seems that the entrance to the tunnels was filled in on purpose, which I think is lame.
If you haven't found some fun things to do on Lieyu (little Kinmen), this map will give you some ideas, like: Shunagkou Beach, Xihu Lake, The General's Temple, Linghuihu Lake, Chaste Maiden Temple, Donggang Quarry, Bada Tower, Tank Road Start Point, Victory Gate, The General Fort, Lianhu Lake, Maogongshi Coastal Recreational Park, L 36 Barracks, Hujingtou Battle Museum, and more!
Yeah, that's pretty much it. If you have a choice of only one set of tunnels, you should visit Zhaishan Tunnels instead; frankly they are much more impressive.
After our trip to Jiugong Tunnels we caught the ferry back to Kinmen for more exploring on the main island!
There are many tours and activities available on Kinmen, such as SUPing / Paddle Boarding, Intertidal Eco Tour, fishing, clamming, Night Otter Spotting, Handmade Metalworking DIY, and many others.
