Arboretum Park Härle

Arboretum Park Härle is a tree garden on the slopes of the Rhine Valley near Bonn, containing over 800 varieties of trees and shrubs across roughly 4.7 hectares (11.6 acres). The property is divided into several areas with different characters, including an older park section with historic buildings and newer portions featuring lawns and fruit trees.

The park originated in 1870 when a railway company director established a country house and began planting trees on the site. Some original plantings from that era remain in the garden today, reflecting the long development of the place.

The park is named after a former owner and is maintained today by a foundation dedicated to preserving plant collections. Visitors can observe how the botanical specimens are arranged across different sections and which species thrive here.

The grounds are open to visitors, and free guided tours are offered on certain Saturdays and Wednesdays for those who want to learn more about the collection. The best time to visit is between spring and autumn, when the full grounds are accessible.

The park contains specialized collections of coniferous plants like Chamaecyparis, Juniperus, Taxus, and Thuja that are rarely seen together in one place. This careful specialization makes the site interesting for both plant experts and curious visitors alike.
