The U.S. National Arboretum mobile app will help guests navigate the vast grounds of the Arboretum via a digital map. A search feature will allow visitors to explore the collections and other features, learn about available visitor services, and locate a memorial bench or tree with greater ease. Tours, exhibits, events and gardens are programmed into the app to let visitors know in “real time” what they can see during their visit. 


Supported by both the iOS and Android platforms, the app will complement the existing signage and other ways of navigating the Arboretum’s many gardens and other features.
