The arboretum was established in 1975 specifically to test the suitability of foreign tree species for regional forestry.
It contains the 'Kanadaweg,' a trail section modeled after the ecosystems of the Canadian west coast.
The project includes significant populations of the Giant Sequoia (Sequoiadendron giganteum), which are monitored for their climate resilience.
The forest is maintained without chemical pesticides, relying on natural ecological cycles for plant health.
Certain sections serve as 'provenance trials' to compare how trees from different latitudes perform in the Harz environment.
Weltwald Bad Grund is a 60-hectare arboretum situated in the Harz mountains, featuring over 600 species of trees and shrubs from North America, Asia, and Europe. It serves as a living research facility for the Lower Saxony State Forestry Office to study how non-native tree species adapt to the Harz climate. The forest is organized into geographic clusters, allowing visitors to walk through distinct botanical zones. Well-maintained trails wind through the woodland, including segments designed for accessibility. Information markers throughout the park identify tree species and provide ecological background. It functions as an experimental forest, meaning the planting patterns prioritize scientific observation over aesthetic landscaping. The location is known for its wide variety of coniferous species from the Pacific Northwest, including giant sequoias. Visitors encounter varying topography ranging from flat meadows to gentle mountain slopes.

Bring a pair of sturdy, waterproof hiking shoes, as the paths can be muddy after rain.
Download the digital map or take a photo of the entrance board, as cell signal can be inconsistent inside the forest.
Pack snacks and water, as there are no food vendors located within the boundaries of the forest.
Do not attempt to traverse the steep, unmarked slopes, which are part of restricted research zones.
Stay on marked trails to protect the ongoing scientific experiments and do not remove plant material.
