The Thielke Arboretum of Glen Rock is a serene oasis in the midst of a busy suburbia.  The arboretum is a wetland forest, with nature trails, gardens, a spring fed pond, and a sparkling brook.  The arboretum's eleven acres support many species of trees and plants, the majority of which are native to this area.   The arboretum also has many trees recommended by Rutgers, the State University, for planting in New Jersey residential landscapes.  The arboretum is a natural habitat for birds, butterflies, amphibians and a water fowl as well as other native inhabitants of the animal kingdom.

The antique Gazebo, located at the end of the 2000 Millennium kousa dogwood allee is a popular site for special occasions and celebrations. The Thielke Arboretum has a well rounded education program, offering New Jersey Core Curriculum based nature tours, for grades pre-kindergarten through high school science classes, and environmental groups  as well as  nature tours for adults and visitors. Tours are led by knowledgeable volunteer docents.
