At least take time to visit citycentre and park(s) by Pavlik_NL
When visiting Arnhem you absolutely must: Arnhem is a green town, the longue of The Netherlands, and you miss what Arnhem is about if you do not visit one of the parks. Most recommendable is Sonsbeek-park just around the corner of the centre. This romantic park lies around the Jans-creek, a little river running downhill towards the Rhine and the birthplace of the town. Fountains, waterfalls and the long green foresty lanes will give you the idea that you are not in a town at all. This park connects with park Zijpendaal, where the same named castle can be visited (classical interior). Best time to walk in the parks is April/May. The town-flower is the Rodondendron, which in this season makes the park bath in red, pink and white blossoms. Other parks: Presikhaaf, Meinerswijk (riverlands), Angerenstein, Mariëndaal, Rosendael and Immerloo.Sitting with some good friends at a Rhinekay-terrace, drinking a good glass of wine when slowly the summersun sets, or,
