The Dutch king Willem Alexander and his wife Máxima reside at the Royal Estate ‘De Horsten’, which is largely open to the public. For a truly royal sensation, come and enjoy a high tea at this former hunting lodge in summer, or watch the magnificent autumn colours of the trees at the estate later in the year. From here, it is only a short walk to Duivenvoorde Castle, one of the oldest castles in the province of Zuid-Holland.
