Visiting the Very Large Array

Tours and Events

Sylvia Kowalski, VLA Operator

Open House

The VLA normally hosts two open houses a year – one in October and one in April. Open House events are free but require advance timed-entry admission. The day includes free tours and talks by NRAO staff and opportunities to meet and speak with VLA operations personnel. Additional NRAO staff are on-hand throughout the day answer your burning questions about anything and everything. Please check our calendar of events for details.

First and Third Saturday Guided Tours

The VLA hosts three guided tours on the first and third Saturday of each month at 10:00 a.m., 12:00 p.m., and 2:00 p.m. Guided tours require no reservations in addition to your advance admission purchase. Simply show up at the VLA Visitor Center 30 minutes before the desired tour time. These guided tours last about one hour and give visitors unique insight into the past, present, and future of the VLA. Staff and VLA Volunteers are on hand to answer questions. All upcoming tour dates can be found on our calendar of events.

For education and special interest groups of 10 or more individuals, we provide private guided tours when possible. We require at least three weeks notice to arrange a guided tour. To request a guided tour for your group, please fill out this Guided Tour Reservation form:
