"Scary looking places"?
Could you point some out to us, please?
There are quite a few of those "scary looking places", even inside the villages, but no really DANGEROUS places anywhere I'm aware of. There are a few aggressive, free-running dogs around, mainly in an area behind Tai Peng Village, but they usually only bark and attacks are very rare.
Even the Quarry is usually very safe and I've personally never met ANY dogs in there while hiking or biking in there occasionally.
I'd go practically anywhere on Lamma during daylight, without any real worry about dangerous wildlife, but I don't venture outside the villages much at night, except for group bootcamps.
So who could tell us more about the safety of jogging, hiking or biking alone at night? Any bad experiences?
