Groups and Buses

Argonne Open House on Saturday, June 27, 2026

Argonne’s Open House offers attendees the opportunity to register with their dedicated group such as boy scouts, girl scouts, community groups, etc. Groups with minors (under the age of 18) require 1 adult chaperone for every 12 minors.  

If the group would like to attend and arrive in separate vehicles, you will need to register each vehicle coming on-site through our public registration site. Each vehicle must have their own ticket for entry.

For groups arriving together on a bus or large van, you will need to register through the group registration site. All attendee names and ages must be submitted to events@​anl.​gov using the template found on the group registration site no later than Friday, June 12.

Drivers must drop off passengers at Building 360 before parking in a designated lot for large vans and buses. There will be staff directing drivers to each location.

Questions regarding group registration can be emailed to events@​anl.​gov
