There used to be a ferry somewhere nearby to get to Central Hong Kong Island but now it has been stopped for apparently with a reason: no operator wants to run it!
That was just a rant and here's about the cache. If you believe in Geomacy, come study Ground Zero. You will be among some fascinating scenic view(on a good day) and an exceptional ambient(on a good night). A couple came to GZ and started to make out while I was averaging GPS signals but they soon went off after they could not have the peace of mind that someone is holding a phone with camera ability within such a proximity.
Do bring your own writing tools and enjoy the surroundings. Try not to smoke.
