Delta-01 Launch Control Facility Tours

To see Delta-01, visitors need to attend a ranger-guided tour. Due to the size of the elevator and the confined space underground, tours are limited to 6 visitors at a time. Tour availability is subject to change due to staff availability, inclement weather, and other factors.

  • Ranger guided tours are available daily. In the summer of 2016, six tours per day will be offered.
  • Tickets are required and are given out on a first come, first served basis, at the visitor center, on the day of the tour.
  • As a safety precaution, all tour participants to the underground portion (the Launch Control Center or LCC) must be at least six years old and 40 inches tall. All participants must also be able to climb two 15 foot ladders, unassisted, as an emergency egress should the elevator malfunction.
