If you are tired of urban attractions, take time out in Utrecht University's tranquil botanical garden. At the old Hoofddijk fort you can admire flora such as alpine plants from all over the world. The bunkers of the fort have been transformed into largest rock garden in The Netherlands, which is complemented by hill brooklets and a waterfall. The outer wall of what used to be the moat is now covered in plants that have always thrived in the river district of the province of Utrecht. Near the Fort you will find one of the few systematic gardens still known in The Netherlands. This garden, which was granted an award for its design, gives you the opportunity of acquainting yourself with the major plant families and their mutual relationship. Systematic gardens are originally intended for teaching botany students. Information is clearly posted, so the garden is also very educational for laymen.
