Hoge Veluwe is the country's largest national park and home to the wonderful Kröller-Müller Museum. The park itself covers 5500 hectares (13,500 acres) and is a strange mix of forests and woods, shifting sands and heath moors that provide a sense of isolation (if not actual isolation) found nowhere else on the Dutch mainland. Red deer, wild boar and mouflon (a Mediterranean sheep) roam here. The Kröller-Müller Museum has 278 works by Van Gogh, as well as smaller collections of Picasso and Mondrian. Hoge Veluwe is accessible by bus from Arnhem.
