Aubonne valley arboretum
The Arboretum is a botanical collection of trees and shrubs, more than 3000, from all the temperate zones of the planet. It was created in 1968 in the Aubonne valley, in the canton of Vaud, Switzerland. Located in the municipalities of Aubonne, Montherod and Saint-Livres, between 500 and 670 m above sea level, it covers an area of 130 ha within an agricultural and forestry site of around 200 Ha. It is crossed by the Aubonne which, coming from the north, is joined by the Toleure, coming from the west. The river, which keeps the name of Aubonne, continues in a south-easterly direction and empties into a dam lake into which the Sandoleyre also flows. The Aubonne then leaves the arboretum at its south-eastern end to join Lake Geneva.
