Houtkampweg 6, Otterlo
Kröller-Müller is a couple hours outside of Amsterdam—you can get there by train/bus—and it is so worth it. The museum was a lifelong dream of a woman named Helene Kröller-Müller, who had one of the largest private collections of art the 20th-century has seen, acquiring close to 11,500 works of art with her husband between 1907 and 1922. The museum, which opened in 1938, is located in Hoge Veluwe National Park. The Kröller-Müller sculpture garden is one of the largest in Europe, with more than 160 sculptures on display from artists like Aristide Maillol, Marta Pan, and Pierre Huyghe. The museum is also home to the second-largest Van Gogh collection (after the Van Gogh Museum in Amsterdam), as well as works by Monet, Seurat, Picasso, Mondrian, and more.
