Japanese tunnels below Jardine's Lookout [????- ]
Thanks to craig for introducing this one:
The best and biggest I've come across- not for the faint hearted- is on the way down the HK trail from Jardine's lookout about 50m before the bottom, near the Quarry (before H057 marker). As you come down all the stairs, down on your right side you'll find a big entrance that has been mostly filled in but with a big enough hole to go in. it opens out into a big chamber with number other tunnels and side rooms. WARNING one tunnel near the back is FULL with BATS which scared the @#$% out of me the first time. I went back a second time prepared with long clothing and gloves. We were very quite and the bats didn't seem to mind us being there looking around the other tunnels. There were a few flying around and as I recall hundreds lining the ceiling. It was a bit hair raising, But quite interesting being inside.
We visited this tunnel last weekend, and I'd agree with craig that it's the biggest and best I've seen too. We took a video walking from the inside of the tunnels back outside. It was taken with a digital camera and processed afterwards to make it brighter - but apologies for the dark sections.
The other tunnels I've seen are low and narrow - just wide enough for one person, and low enough that you have to stoop most of the time, and occasionally crouch or crawl. In this network some of the connecting tunnels are like that, but there are also several large, square caverns that have been excavated, so it must have been planned for some different purpose.
Some of the sections slope up or down, so they are on different levels. Several of the caverns have loose earth and rocks sloping down from the ceiling to the floor. I guess these were other large entrances that were filled in from the outside to block them up after the war. The other thing you'll see at several places are grooves cut into opposite walls. I wonder if they were to mount frames for doors or gates?
Here's the video:
If you know anything about the history of these tunnels (who built them, what they were intended for, when they were filled in, etc), we'd love to hear from you.
