It is a National Natural Landmark and a State Nature Preserve owned by the City of Evansville and operated by the non-profit Wesselman Nature Society. The preserve consists of over 190 acre of virgin bottomland hardwood forest complemented by an additional 50 acre of younger forest, field, and pond. The woods consist of sweetgum, sugar maple, tulip tree, Shumard oak, and green ash throughout. It is the largest tract of virgin forest located inside any city limits in the United States. The oldest trees are over 400 years old. Among the largest of their species are 24 state champions and two county champions.

The woods offer a variety of hiking trails of varying distances. The amphitheater near Odonata Pond may also be rented for outdoor activities.
