The UT Arboretum is a place for all seasons! Walkers can enjoy our over five miles of Walking Trails year round. There is always something in bloom at the Arboretum and our Featured Plants page showcases a different plant each month. Bird and Wildlife spotting is common during every season and holly berries abound in the Elmore Holly Garden during the holidays. Enjoy a virtual tour of the Arboretum via our Photo Gallery. The Arboretum and Arboretum Society hosts spring and fall plant sales, seasonal workshops, timely lectures, and special guided walks - even on New Year's Day!

The Arboretum Society

The University of Tennessee Arboretum Society (UTAS) is a non-profit organization of volunteers from throughout Tennessee, dedicated to furthering the objectives and programs of the Forest Resources Research and Education Center's Arboretum Project in Oak Ridge, Tennessee.

Chartered in 1965, the Arboretum Society has assisted the Arboretum by providing support and funding for such projects as expanding plant collections, constructing facilities to enhance the public's use and enjoyment of the Arboretum, and informing the public of the unique value and importance of the Arboretum to the area. Recently, the Society accepted the challenge of providing a portion of the operating funds needed to assure continued public access to the Arboretum.

Information about the Society and membership opportunities are available at the UT Arboretum Visitors Center or by e-mail at

Inclement Weather

Please be advised that the UT Arboretum follows the same weather closures as the Knoxville Campus. In the event that our staff cannot make it in and/or the conditions are deemed unsafe, we will close the UT Arboretum and the gate will be up and locked. We ask that you refrain from entering the property at any time the gate is locked.

Professional Photographers Policy

The UT Forest Resoures AgResearch and Education Center (FRREC)/Arboretum is proud to provide an attractive venue for all types of outdoor photography in the East Tennessee region. However, considerable materials and labor are required to maintain the UT FRREC/Arboretum to the high standard that has attracted so many professional photographers for their photography sessions. As a result, starting on July 23, 2014 the UT FRREC/Arboretum will implement a new Photography Policy. Click here to view the new Photography Policy.
