Longmen Military Tunnel Half-Day Walk: Reading Penghu's Wartime Memory in Huxi

When traveling around Huxi in Penghu, many visitors save their time for Kueibishan, Qingluo Wetland, or Lintou Beach, while Longmen Military Tunnel often stays on the backup list. It is actually a strong half-day walk: not just a military photo stop, but a route connecting tunnels, settlement life, windbreak forest, harbor coast, and wartime memory. If you want to understand more than the sea views, Longmen is worth slowing down for.

According to the Penghu National Scenic Area Administration, Longmen Nankan Military Tunnel was planned by Penghu County Government as a military-culture attraction after being handed over by the military, and it opened after completion in October 2020. The site is broadly divided into an outdoor landscaped area and the inner Longmen tunnel. The main tunnel structure was built during the Japanese colonial period, about 705 meters long, 60 to 80 centimeters wide, and about 2 meters high; machine-gun bunkers, anti-aircraft gun bunkers, an underground command post, radar station, and other facilities were added after the National Government forces took over.

First See Longmen as an Underground Route

The point of Longmen Military Tunnel is not to finish it quickly, but to understand how the space served defensive needs. The narrow tunnel, long route, walls, turns, and combat spaces make it clear that concealment mattered more than comfort. On a first visit, build your sense of direction from the entrance information, outdoor steel sculpture, and the surrounding coast before entering the tunnel to observe the military facilities, without rushing to photograph every corner.

Four Details to Notice On Site

• Tunnel scale:The roughly 705-meter underground space is not short, and its width and height make clear that it was not designed for tourist comfort. If traveling with elders, children, or anyone uneasy in enclosed spaces, assess suitability first.
• Combat facilities:Machine-gun bunkers, anti-aircraft gun bunkers, ammunition rooms, kitchen, war-game room, and guard spaces show that the position was not just a shelter, but a functioning defense node.
• Murals and maps:In the war-game room, murals by Penghu artist Zheng Meizhu cover themes including the 1895 Japanese landing in Penghu, the Japanese-era tunnel excavation, and Longmen's location map. Slow down to read the images and text.
• Fish Leaping Over Longmen steel sculpture:The outdoor steel sculpture combines the place name, the old image of Longmen waves, and the tunnel lines, making it a good transition from underground space back into island light.

How to Plan a Half Day

First Visit: Keep the Stops Few

Plan Longmen Military Tunnel as part of a Huxi half-day route, rather than forcing it into a packed cross-island schedule. Start with the entrance and outdoor landscape, enter the tunnel, then leave time for Longmen Harbor or other nearby Huxi stops. If the day is windy, sunny, or your group has moderate stamina, one fewer stop is better than rushing all day.

History Lovers: Match Names to Space

As you walk, notice the spatial logic behind the name military tunnel: entrance, command, storage, firing fields, observation, and exit routes relate to one another. Do not treat the tunnel only as a cool photo background. Once you connect facility names with their locations, you can see the defense role Penghu carried in different eras.

Families or Elders: Slow the Pace

The tunnel may be dim and narrow, and it may not suit every mobility condition. With children or elders, confirm notices, route limits, and suitability before entering. Inside, use short observation tasks, such as finding the exit direction, looking at murals, or identifying combat spaces; the visit does not need to become a test.

Before You Go

1. Check official opening hours, visit method, tickets, closure days, and on-site notices; do not rely on old travel posts.
2. Wear comfortable non-slip shoes, and walk steadily through tunnels and boardwalks; do not run, jump, or move against the route for photos.
3. If anyone is uneasy in enclosed spaces, has mobility limits, or travels with very young children or elders, confirm route limits and exit options first.
4. Respect the military-culture site: do not touch restricted facilities, cross barriers, or turn wartime spaces into risky challenges.

Make Huxi a Layered Half-Day Trip

What makes Longmen Military Tunnel memorable is the way it puts Penghu's coast, wartime landscape, windbreak forest, and local reuse into one route. After leaving the tunnel, the view of Longmen Harbor and the Huxi coast feels different: this is not only an underground military hideout, but also a place reorganized by time into tourism and education.

To plan Longmen Military Tunnel, Kueibishan, Qingluo Wetland, or the Huxi coast into an unhurried half-day route, share your travel date, lodging area, group size, and themes through Chaolui International Travel itinerary consultation. We can help arrange stop density, transport order, and weather backup plans. Actual opening hours, visit method, tickets, and on-site operation should still be reconfirmed with official sources or licensed operators before departure.
