Nice city, a few hazards
Hong Kong is a great city with a lot of amazing sights. The public transportation system can be a little confusing at first, but it's great and covers almost everything on the islands. It can also get you between the islands, no problem. Many of the museums, etc. are very cheap and are very interesting. The only real problem I had was with the severely uneven sidewalks and pavement. If you have weak ankles or knee problems, you'll want to bring some sort of support.
