Amsterdam is also called the City of Canals for its small yet wonderful waterways that crisscross the capital city. Take a look at them and you will know that this the way Amsterdam is meant to be explored. On the sides these canals are heritage houses and warehouses, some of which were build in the 17th century. There are in all 1,281 bridges that cross these canals. The best time of the day to take a cruise is just after dusk, when the illuminated houses on the side with the dark grayish sky in background provide a romantic setting.
