What Travellers Say
Reviews Summary
Visitors consistently praise the Green Bank Observatory for its awe-inspiring scale, unique 'Quiet Zone' experience, and informative visitor center. The knowledgeable staff and the stunning natural setting, especially during autumn, are frequently highlighted as major draws. Some minor inconveniences include limited on-site amenities and the challenges of navigating the area without reliable cell service.
"The Green Bank Observatory is one of the most unique and awe-inspiring places I’ve ever visited. The sheer size of the Green Bank Telescope is mind-blowing — seeing it up close, framed by the fall colors of the Appalachian Mountains, is an unforgettable experience. The setting is peaceful, quiet, and surrounded by beautiful rolling hills that burst into color during autumn.
The visitor center is excellent — very informative with exhibits explaining radio astronomy, the science behind the telescope, and the special “Quiet Zone” that protects it from radio interference. The staff and guides are extremely knowledgeable, patient, and passionate about the science they do here.
One of the most interesting aspects is being in an area where there’s no cell service or Wi-Fi due to the National Radio Quiet Zone. It’s a refreshing digital detox — you really get to slow down, take in the surroundings, and enjoy the moment."

"This place is absolutely incredible! Once in a lifetime experience, and a MUST see! We seen videos on the GBO and were obsessed so we planned our honeymoon for West Virginia and Virginia so we could see it for ourselves! At over 17million pounds and 2.3 acres big, it is the largest rotating radio telescope in the entire world and to see it in person and learn about the history and the technology ban in the area, it was so amazing and impressive to be able to see and learn in person to say the least! Also, gift shop was super nice with great prices and the staff were very friendly snd knowledgeable :) 12/10 would recommend!"
