High Tech Tours are offered the 2nd Thursday of every month.
$25/person
Join an Observatory engineer for an in-depth conversation and behind-the-scenes peek at our electronics lab, telescope receivers, and the GBT control room. See what makes our observatory one of the world’s leading radio telescope facilities!
3:30 p.m. ~ 5:00 p.m. Tour lengths will vary slightly, but plan on approximately an hour and a half.
Advance reservations required. 15 participants max; recommended for ages 16 & up. A clearance check is required to allow access to our restricted laboratory spaces. Please be sure to submit your Visitor Registration Form [1] at least 72 hours in advance to allow ample time for your clearance to come through.
Purchase tickets from our Online Shop [2]. This tour does tend to sell out most of the year; if you are traveling with a group, we recommend purchasing all tickets together.
Interested in seeing the telescopes as well? Come early and add a Guided Bus Tour to your itinerary! A 2 PM tour will get you back to the Science Center in time for the 3:30 High Tech tour. Tickets are available in our Online Shop [3] about a month in advance.
