Plan Your Visit to the VLA
The Very Large Array Radio Telescope facility is a two-hour drive from Albuquerque, 50 miles west of Socorro, New Mexico. The Visitor Center features an award-winning documentary narrated by Jodie Foster, plus exhibits describing radio astronomy and the VLA telescope. A self-guided walking tour features large, informative signs and takes you to the base of one of the giant dish antennas. A gift shop offers VLA souvenirs and educational materials.

The Visitor Center is open every day from 8:30am until sunset. Upon arrival, please check in at the Gift Shop to pay admission and receive your informational brochure. You are free to explore our exhibits, where you will learn more about radio astronomy and the role the Very Large Array and other NRAO telescopes play in current research. A 5-minute silent video will show you how we move antennas. In the auditorium is a 23-minute documentary, produced in 2013 and narrated by Jodie Foster. The documentary is an overview of radio astronomy, interferometry, and the VLA itself.
Tours & Events
The walking tour will take you to our Radio Sundial, past our Whisper Dish Gallery, on to our Radio Astronomy Gallery, and finally to the base of one of the 230-ton working antenna on the array! From there you will head toward the control building’s outside staircase to the observation deck for a view of the array itself and details about the supercomputer processing taking place inside the control building. The walk returns you to the Visitor Center where you are welcome to browse through our Gift Shop for unique souvenirs. The Gift Shop opens almost every day at 9:00am and closes at 4:00pm.
We suggest you make a right-hand turn as you leave the Visitor Center parking lot and head for the tall yellow building, following the signs for the AAB (Antenna Assembly Building) Tour. As you cross the railroad track there is a parking lot on your left. From there you may view our 28th antenna that may be undergoing routine maintenance. VLA Transporters are often parked in this area as well.
You are welcome to take photographs of everything you see, but please keep your cell phone turned off or put in airplane mode (otherwise it interferes with our observing).
First Saturday Tours
The VLA hosts three guided tours on the first Saturday of each month at 11:00 a.m., 1:00 p.m., and 3:00 p.m. No reservations are required, simply show up at the VLA Visitor Center 30 minutes before the desired tour time. These guided tours last about 50 minutes and take visitors to areas behind-the-scenes at the VLA. Staff and VLA Volunteers are on hand to answer questions. Once again, no reservations are required.
The First Saturday Tour event culminates in an evening of free Guided Night Sky Telescope Viewing at the Etscorn Observatory on the Campus of NM Tech located in Socorro. The night time event begins at dark and lasts two hours*, no reservations required.
*This event takes place despite cloudy nights or other weather issues that keep us from being able to use optical telescopes. If the weather conditions are not favorable for telescope viewing we host visitors inside the Observatory classroom space offering a Q & A “Ask an Astronomer” session that may last 30 to 45 minutes only.
(After 6:00PM on First Saturday call Judy Stanley at 505-515-5780 if you have questions or concerns)
Third Saturday Tours (NEW in 2018!)
Beginning in 2018, the VLA will now host three guided tours on the third Saturday of each month at 11:00 a.m., 1:00 p.m., and 3:00 p.m. No reservations are required, simply show up at the VLA Visitor Center 30 minutes before the desired tour time. These guided tours last about 50 minutes and take visitors to areas behind-the-scenes at the VLA. Staff and VLA Volunteers are on hand to answer questions. Once again, no reservations are required.
No night sky viewing is available at Etscorn Observatory for Third Saturday events at this time.

More To Do in the Area
Wondering what else to do while you’re in this unique area? There’s plenty more! Our neighboring cities of Socorro and Magdalena offer art studios, shopping, and dining. Beyond the VLA to the west are Datil and Pie Town, offering unique dining experiences.
Photography and Filming
As noted above, visitors to the VLA may photograph what they see from the designated self-guided walking tour. However, any filming or photography done by a commercial or professional entity, or that is done by anyone, amateur or professional, from areas not authorized for general-public tourists or outside the hours authorized for general-public tourists, is considered to be “commercial.” Such photography must be approved in advance, and requires completing an application process, coordinating with NRAO staff, and payment of fees.
There are no exceptions. Any nighttime photography or any photography from anywhere other than the designated walking-tour path requires going through the advance-approval process and paying all fees. This applies to everyone, amateur and professional alike.
Full information on commercial photography and filming, along with the required application form, is provided below. Please return application to firstname.lastname@example.org.
