If you'd like to inject a little more culture into your vacation, put Tung Wah Museum on your travel itinerary. See if guided tours are available or just look around at your own speed.
When you've finished at this museum in Mong Kok, why not make your way to Ocean Park, Lan Kwai Fong, and Harbour City? They're not too far from Tung Wah Museum and also a favorite with tourists.
