Visitors & Tours

Welcome to the
Savannah River Site
Tour Program

The SRS complex covers 198,046 acres, or 310 square miles, encompassing parts of Aiken, Barnwell and Allendale counties in South Carolina, bordering the Savannah River.

Dedicated to maintaining the highest possible safety and security standards, the Savannah River Site (SRS) is a key U.S. Department of Energy industrial complex, responsible for supporting our nation’s nuclear defense; preventing nuclear weapon proliferation; environmental stewardship and cleanup; waste management; and disposition of nuclear materials. More specifically, SRS processes and stores nuclear materials in support of the national defense and U.S. nuclear non-proliferation efforts. The Site also develops and deploys technologies to improve the environment and treat nuclear and hazardous wastes left from the Cold War.

The Site is owned by the U.S. Department of Energy and managed and operated by Savannah River Nuclear Solutions, LLC, a partnership formed by the Fluor Corporation with HII. SRNS is responsible for the Site’s nuclear facility operations; environment; safety; health and quality assurance; and all the Site’s administrative functions.

SRS Public Tour Program

In 2026, Savannah River Nuclear Solutions, LLC will offer the public twenty-one driving tours of Savannah River Site (SRS), as well as two in-depth walking tours of the site of the historic former town of Ellenton, providing openings for approximately 700 members of the public.

All tours will begin at the Savannah River Site Badge Office. (see attached map) Guests will be given an overview presentation, safety and security briefing and driving tour of the site. The Mission Related Public Tours will include a general site driving tour along with a visit to the University of Georgia’s Savannah River Ecology Laboratory (SREL). At SREL, visitors will get an overview of the ecology lab’s history and mission and get an up-close view of animals that are native to the Savannah River Site.

Due to high demand, there will be six Historic Tours available in 2026! In addition to three tours that will stop at the Dunbarton Town site in March, we will offer three tours that will be going to the Ellenton Town site in October. All Historic tours also include a tour of the SRS Curation Facility and a driving tour of C Reactor. For an in-depth dive into the history of the Savannah River Site to supplement your Historic Tour, consider planning a visit to the SRS Museum located in downtown Aiken. Admission is free and the museum is open Wednesday through Saturday from 10 a.m. to 4 p.m.

Site tours provide an opportunity for those interested in SRS to better understand the Department of Energy’s facilities, missions, and workforce that changed the face of Aiken, Barnwell and Allendale Counties, nearby cities and helped win the Cold War. Guests will also learn about facilities supporting current and future missions of the Savannah River Site for both Environmental Management and the National Nuclear Security Administration.’

All tour participants must register separately, with separate email addresses.

Each participant will be asked to provide their Social Security Number during registration for security purposes. If you choose not to provide the information, you will not be allowed to participate in the tour.
