Amsterdam's centre is enjoyably small-scale, though finding your way around the canal belt can be confusing. The old city is contained within the ring of concentric canals dating from the 17th century that form the crescent-shaped canal belt bordered by the Singelgracht. Think of it as half a bicycle wheel: the medieval city around Centraal Station is the hub, and several main roads, minor canals and the Amstel River function as spokes.
Dam Square, five minutes' walk south of the station, is the centre of town, but there are several other happening 'centres', all within walking distance: Leidseplein, with much of the city's cultural life and nightlife, Rembrandtplein (nightlife), Spui ('intellectual' life) and Museumplein (culture) are just some of the focal points that make the city a joy to explore on foot or by bicycle.
Centraal Station, the central train and bus station, lies on the south bank of the IJ. The airport at Schiphol is 18km (11mi) southwest of the city centre.
