The Netherlands is a small, densely populated country, a land of colourful tulip fields and canals, sophisticated cities and some of the most striking coastline in Northern Europe. The people, language, and culture of the Netherlands are referred to as "Dutch". At the head of the state sits the country's constitutional monarchy, whose palaces dominate many of the larger cities, including The Hague and the gorgeous capital city, Amsterdam. Its small size, welcoming attitude to travellers and many wonderful sights make it a unique and fairly easy to discover destination and a great addition to any European trip.
