a reasonable question - especially as we've recently 'discovered' about five crags that are all located on the same island containing the main sport climbing crags in HK, Tung Lung...
I guess the main reason that myself and others had missed these (I've been visiting Tung Lung for >20-years now..) is that we always turned left when getting off the ferry and headed towards Technical Wall etc. Following a little tip off, I decided to 'swipe right' for a change and went for a wander to the other side of the island. Currently feeling quite chuffed that I did given what we found... Also quite nice to try and get a bit more of a trad ethic going as most things get blitzed with bolts normally
Before anyone asks, apparently the cliff's were painted white [waaaaay] back in the day as a visual aid to pilots making their final approach to Kai Tak - god knows what they did when the weather was bad tho...
