About

LLNL is a Department of Energy laboratory with a secured main site. The Discovery Center, in the Livermore Valley Open Campus outside the main site, is an exhibit hall you can walk into on weekdays, with a replica of the National Ignition Facility target chamber. The lab also runs a separate guided main site tour, with a docent and a small group, that includes the National Ignition Facility; it requires registration (no drop-ins) and entry to the lab is badged. The tour pages do not give its dates, eligibility rules or how far ahead to register, so check them before you plan.
