A potential tunnel facing the pillbox near Pok Fu Lam Reservoir. This entrance is within 4 to 5 meters south (slightly to east) from the pillbox. It is almost silted up, like the North-West entrance.
There's a large entrance:
Learned about it from a few online sources, also Mr. Cracknells blog as I recall. Went and looked through it this summer. Figured I would add it here. It is reasonably long, going through a ridge I think, 2 exits and a somewhat long side tunnel as I remember. One exit overlooks the reservoir.
The main access point is right off the staircase leading up from the crossroads of Mt. Parker road/Boa vista track. it is only about 50 or so meters up the staircase just past a power station. The entrance is large and obvious.
With @Mike B and Lawrence on the very start of Blacks Link (where the main road joins the access/country park road), there is a Japanese tunnel off to the right. It goes right into the concrete slope via a small gap that has opened up through the cement somehow. The opening is small but we squeezed in. It opened up and had a number of bends and even a small set of stairs. @Lawrence noted it had a few splits towards the end and I believe we estimated the length as around >40 meters. I have a low quality video but I think we will try to map it out soon.
A single tunnel extending into hillside. Entrance is largely silted up but it opens up a bit and extends sloping up into hillside, could be more entrances around. North-West of the PB around 30 meters or so. It is along a ravine next to a pipe line running down from the edge of the covered reservoir area toward HKU buildings.
The "Hiking Trail HK" App (avail on Android) shows a Japanese Tunnel here.
I have passed by recently but couldn't see anything.
Can anyone verify this place or has more information?
Directly behind the AOP Matilda a tunnel entrance in N direction leads into a system with 2 further exits. One exit in W and one E direction of the ridge leading up to Matilda.
Very easy to reach, just climb over the railing at the very southern grass lawn edge from Matilda and head down the ribbon trail for about 40m until you hit the British built AOP.
Just a short stroll from Hong Pak Country Trail there's a Japanese Tunnel System dug into the slope. I remember 3 entrances/exits. 2 of which are easily accessible.
Best access is from the Hong Pak Country Trail. You will pass by another open Japanese tunnel just off the trail. Continue slightly uphill again to the flat plateau where you find a slightly confusing network of small trails.
Follow the one leading down the ridge and you won't miss it.
Just 20m West off Hong Pak Trail (A ribbon path will guide you) once can find an open and easy accessible Japanese Tunnel Entrance. To the left of this tunnel on the same side of the hill there's another 3 potential but now covered former tunnel entrances. Just follow the the relatively short concrete water conduit for about 60m.
Does anyone have any aerials from the area from WW2?
There's a myriad of small paths in the area, not all have ribbons or are on hiking/gov apps&maps.
I saw this on Wednesday, while heading to the top of Kowloon Peak for the first time. We took the trail that runs straight up the hillside from Fei Ngo Shan Road, starting from the graveyard. (Switch to the OSM map to see the trail.) There's a sign at the start saying the trail is dangerous, but though it is steep it is clear, and has steps.
The position of the marker is approximate, but the tunnel was on the right side of the trail, about three quarters of the way up.
