Last week we went to the National Park De Hoge Veluwe. This is the largest nature park in The Netherlands. At night, the gates are closed, but during the day this is a beautiful spot for walking and cycling. If you go there by car, the best thing you can do is to leave your car at one of the entrances, and take one of the 1700 white bicycles that all visitors can use for free. Great system!
Inside of the park, there is also the museum Kroller Muller, with a beautiful collection of late 19th and early 20th century art.
