Having spent time in Hong Kong, we made a day trip to the New Territories, which is part of mainland China. Walking among skyscrapers and about 7.5 million people, it is sometimes hard to remember that you are on a relatively small island. In fact, Hong Kong’s airport is on a separate island, Lantau Island, but the two are connected by roads and train almost seamlessly.

There are more, smaller islands in the South China Sea and we took the ferry to Cheung Chau island, where pirates once roamed.
