Aiken is home to one of the most diverse collections of trees found in any municipal landscape. Oaks from around the world along with many rare tree species dot the landscape and fill the parkways of Aiken. Aiken’s Citywide Arboretum includes everything within a 4-mile radius of downtown. However, we encourage you to begin you exploration by discovering Colleton Avenue, our designated Arboretum Trail. The trail includes exploration through the use of your mobile cellular device. Simply dial the number listed on the label identifying the tree to learn about the tree represented by that specimen.Trail begins at the Aiken County Public Library, 314 Chesterfield St. S. To access the Mobile Tour, simply dial (803) 295-5008 and enter the each tree’s number as posted.
