Utrecht is packed with medieval charms and a range of museums. Sure, the weather isn’t always great but there’s still plenty to do! The best time to visit is in the summer months, when you can usually wander Utrecht’s outdoor attractions in the sunshine. The busiest month for tourists in Utrecht is December, followed by August and January. Hotel and flight prices are more expensive during these months, so remember to book early! Or come in the relative quiet of June or September.
