Hong Kong’s KCR (5.30am-1am; every 3-10min) serves the New Territories with three lines: KCR East, running via Sha Tin, Tai Po and Sheung Shui to the Chinese border at Lo Wu (you can only go as far as Sheung Shui without a Chinese visa); and the Ma On Shan Line and KCR West, which are of less use to visitors.

One-way tickets cost between HK$3.50 and HK$9 depending on the length of your journey, with a first-class compartment for double the standard fare. There’s a HK$100 fine for fare evasion, or travelling first-class with an ordinary ticket.
