Come see us

Oak Ridge National Laboratory hosts thousands of visitors every year. The information below may help make your visit more productive and enjoyable. If you have any questions about visits to the laboratory, please contact ORNL Visitor Services at or 865.574.7199.

Before Arriving

ORNL welcomes visitors to the Laboratory. However, because of increased security requirements, we've made some changes in how the site is accessed.

Bethel Valley Road, which is the main access route to Oak Ridge National Laboratory from both directions, is now closed to the public. If you are planning a visit to ORNL, your host will arrange for you to proceed past entrance stations on Bethel Valley Road leading to the Laboratory's Visitor Center. Please be aware that effective March 30, 2015 ORNL will/has become fully compliant with the REAL ID Act.  This Act requires that anyone accessing a Federal Facility, which ORNL is, must present a compliant form of identification.  If you are from one of the noncompliant states, you will need to provide another form of approved identification. Here is a list of acceptable identification if you are from one of these states.   You will not be allowed entry to any ORNL facility unless you have a form of compliant identification as listed above.  

Foreign national visitors must always present a Visa and Passport upon arrival at the ORNL Visitor Center.

It is very important, if you are not a DOE or DOE contractor employee, to arrange your visit to ORNL ahead of time.

If you're not sure how to arrange your visit, contact ORNL Visitor Services (, 865.574.7199).

Entering ORNL

The Visitor Services Office prepares a daily list of visitors for the Protective Force personnel, which is finalized by 4:30 p.m. EST on the preceding day. Your host or sponsor will submit your name to that list. Upon your arrival at one of the Bethel Valley Road entrance stations, have a compliant form of identification ready for the Protective Force officers so that they can quickly confirm you with the list. You will not be allowed entry to any ORNL facility unless you have a form of compliant identification. 

Foreign national visitors must always present a Visa and Passport upon arrival at the ORNL Visitor Center.

Once verified, you will be issued a Temporary Entry Pass, which authorizes you to travel from the entrance to the ORNL Visitor Center.

Follow the signs directly to the ORNL Visitor Center to receive an ORNL visitor ID, or to the ORNL badge office for badging, as appropriate. If you arrive and are not on the list of registered visitors, your ORNL host or sponsor will then have to verify your visit with ORNL Security. So it's very important that arrangements are made before your visit.

ORNL Visitor Services (, 865.574.7199) can provide you with access to specific Laboratory areas based upon your needed access requirement for as long as your stay requires.

Deliveries to ORNL

Non-DOE badged vendors and delivery personnel delivering goods to ORNL must have in their possession either a bill of lading, purchase order, or shipping order showing the need for access to ORNL and the name and phone number of a point of contact at ORNL who knows about the delivery. Persons in this category who do not have one of the above items in their possession will not be allowed site access. If a bonafide delivery is involved, the delivery vehicle driver will be afforded an opportunity to contact Visitor Services by telephone for needed assistance.

Trucks over 5 tons - As of Jan. 23, 2015, large delivery vehicles are being routed onto Old Bethel Valley Road near ORNL's east portal for security inspections, leaving existing traffic lanes open for ORNL staff and other visitors. The new inspection route will apply to all vehicles with a hauling capacity of at least five tons, including small moving vans or delivery trucks and larger vehicles. Those vehicles will not be permitted to access ORNL from the west end (Hwy 95). Signs will direct trucks to the new route, which will lead to an inspection area near Hawk's Nest Road.

Building Access

Access to many buildings at ORNL is now controlled with a "proximity card reader" system. The ORNL proximity card you receive at the Visitor Services Office should provide entrance into your building simply by placing the card in front of the proximity reader, located beside the doorway. When the light turns green and the door lock clicks, you may enter the building. If your proximity card does not give you access to a desired building, report to the Visitor Services Office.

Wireless Networking

As a visitor to Oak Ridge National Laboratory (ORNL), access to the ORNL wireless network is available to you in many of our buildings. To gain access, you must have a PC or other portable device with wireless capability. If your PC or portable device does not have wireless capability, a limited number of wired-to-wireless Ethernet bridges may be available from your host organization.

The ORNL Guest House is located on the Oak Ridge National Laboratory campus, just a short walk away from the Spallation Neutron Source and within a five-minute drive of any part of the campus, including the High Flux Isotope Reactor and the Conference Center. The Guest House is a three-story, 47-room, 71-bed facility. All rooms have a mini fridge and microwave. Reservations can be made 24/7 by calling 865-576-8101 or you can make an online reservation.

Smoking Policy

ORNL has established a Smoking Policy (view policy excerpt) that restricts smoking tobacco products and use of electronic cigarettes to only designated smoking areas.  Select an area map for the building number that you are in or nearest to.  For example, designated smoking areas for Building 5700 are found on the "4000 & 5000" area map.  Area maps: 1000, 2000, 3000, 4000 & 5000, 6000, 7000, 7600, 7900, and 8600 (SNS).

A Word About Radiation

The ORNL campus includes several research facilities where radioactive materials are present or radiation generating equipment is used.  Additionally, owing to its role in the Manhattan Project and other pioneering activities of the atomic age, ORNL has several historical facilities with legacy radioactive materials that are awaiting or undergoing demolition.  These buildings and areas where radiological hazards may be present are visibly posted as Controlled Areas and are not generally accessible. Unescorted access to Controlled Areas is limited to individuals who have received appropriate training and are wearing an assigned personnel dosimeter (i.e., TLD).  Visitors may be escorted into certain Controlled Areas by their sponsor or host provided they are part of an organized tour or have satisfied the necessary access requirements for the particular area.  Radiological areas across the ORNL campus do not pose any risk to the visiting public when posting requirements and designated boundary restrictions are properly observed.
