China doesn't do things by halves and the Three Gorges Dam proves just that. A massive feat of engineering the dam, at over two kilometres in length, is the world’s largest hydroelectric power station in terms of capacity and energy generation. Controversial as it may be it is difficult to not be impressed by the sheer scale of it, best viewed from the purpose-built platform whilst the visitor’s centre also provides some interesting information about the project. Visiting the dam whilst on a Yangtze cruise means that your ship will have to journey through the massive ship locks that takes river traffic around the dam. There are five in total, each 280 metres long and 35 metres wide.
