Nationaal Bomenmuseum Gimborn (National Tree Museum Gimborn) is the largest arboretum in the Netherlands. The park-like landscape is criss-crossed with winding paths, a large heath garden, unique vistas and an enormous tree house. The ponds are fed by clear seepage water from the Utrechtse Heuvelrug (Utrecht Hill Ridge).

Covering 29 hectares, it houses a world-famous collection of 3.000 species of trees and shrubs from all over the world. German ink manufacturer Max von Gimborn started it as a private collection of conifers and ericaceous plants in 1924.
