WildWoods

WildWoods is a new, outdoor exhibit of Fernbank Museum of Natural History. It features several hands-on elements, an elevated boardwalk, interpretive signage, and a couple of playground areas. In the 1930s, there was a landscaped garden here. A stone wall remains from those days.

Fernbank Forest

Until July 2012, Fernbank Forest was publicly-accessible. At that time, a lease ended, and the property was transferred from the Fernbank Science Center and the DeKalb County School District to Fernbank Museum of Natural History.

In September 2016, it reopened for self-guided tours as part of Fernbank Museum of Natural History. Museum admission or membership is required for forest access.

Fernbank Forest is an old-growth Piedmont forest, with large beech trees, tulip poplars, and 7 trees on Trees Atlanta's champion trees map. Some segments of the forest are very similar to Deepdene Park in Olmsted Linear Park, which is located nearby. In the years while the forest was closed to the public, the museum restored the forest, removing invasive species. Restoration work continues.
