The number of canals have led this city to become known as “The Venice of the North”. And thus, Amsterdam tourism trip is not complete without a boat cruise on these well known attractions in Amsterdam. A canal tour can be both fascinating and relaxing by day and enchanting and romantic at night when many of the houses and bridges are illuminated. The four main city center canals are Prinsengracht, Herengracht, Keizersgracht and Singel. There are also numerous smaller canals in the neighbourhood of Jordaan, of which the Brouwersgracht, the Bloemgracht and the Leliegracht are especially pleasant. If you like boats there is also a large upcoming event about historical sail ships called Amsterdam SAIL.
