Stumbling upon treasures
It was easy to see why Cheung Chau's most notorious pirate had chosen this spot as a hiding place for his loot. The cave is pitch black, concealed by a jumble of boulders, and the entrance is barely large enough to squeeze through.
In fact I was firmly wedged in it, my legs dangling over a four-metre drop to its dank floor. I struggled to take the offending camera bag off my back, thrust it in front of me and twisted to peer behind, torch in hand.
No, I would surely break a leg attempting that drop. I hauled myself back through the opening. It was a bit like drawing a cork from a wine bottle.
Wrong opening. There was a crevice to my left which I had not noticed, very narrow, but once inside my feet felt the rungs of an old iron ladder.
At floor level, Cheung Po-tsai's cave is less than two metres wide, but it is about 12 metres deep, and well above the high tide line: ideal for hoarding.
At the far end there is another narrow opening in the roof, even tighter than the entrance, and with the help of another ladder I forced my way through it and back into the sunshine.
In Cheung Po-tsai's days, it would have been an ordeal clambering over the boulders to reach the cavern, and of course you would not have been too popular with the pirates if you discovered it.
