Hi Dartman,
Never been to HKG, but one of my climbing partners lived out there and reccomends the granite in the area...seriously good routes apparently, but only 2-3 pitches I think he said.
Think there is a mixture of bolted and trad routes, and judging by the number of good HKG climbers I've met in my trips, there must be a good sport/trad thing going there.
Cheers,
Dave
