2 Best Sights in Utrecht, The Randstad

The spectacular Kasteel de Haar is not only the largest castle in the Netherlands, but also the most sumptuously furnished. Thanks to the fortuitous way the Barons van Zuylen had of marrying Rothschilds, their family home grew into a Neo-Gothic extravaganza replete with moat, fairy-tale spires, and machicolated towers. The castle was founded back in 1165, but several renovations and many millions later, the family expanded the house under the eye of P. J. H. Cuypers, designer of Amsterdam's Centraal Station and Rijksmuseum, in 1892. Inside the castle are acres of tapestries, medieval iron chandeliers, and the requisite ancestral portraits snootily studying you as you wander through chivalric halls so opulent and vast they could be opera sets. Once you explore this enchanted domain, you'll easily understand why Marie-Hélène van Zuylen, who grew up here, went on to become Baroness Guy de Rothschild, the late 20th century's "Queen of Paris," famous for her grand houses and costume balls.

Directions for car travelers are given on the castle website. For public transport, take Bus No. 127 leaving hourly from Vleuten Station (10 minutes by train west of Utrecht Centraal), direction Breukelen, until the Brink stop in Haarzuilens, a 15-minute walk from the castle.

Beyond the converted 19th-century station that serves as the entrance to this excellent museum is a vast exhibition space in the style of a rail yard. In addition to dozens of locomotives, several theme zones take you on a tour of rail history. In the Great Discovery, dealing with the birth of the railways, you follow an audio tour (available in English) through an early-19th-century English coal mine. Dream Journey stages a theater production based on the Orient Express. In Steel Monsters, you sit in carriages and ride the rails, while all around you the bright lights, sounds, and billowing steam evoke the Golden Age of train travel. Outside, kids can ride the Jumbo Express on an adventure trip past lakes and through tunnels and water jets. The museum is an easy walk from the city center; alternatively, trains run between here and Utrecht Centraal Station eight times daily (€2.60 one-way).
