Thing to Do
Tour the Front-line of the Cold War at Delta-01
Learn what it was like to have the awesome responsibility of thermonuclear war at your fingertips. The forty-five minute ranger guided tour of the control center at Delta-01 begins with a walk through of the grounds and topside support building. Visitors then descend via elevator 31 feet underground to the Launch Control Center to see the electronic consoles used by missileers to control ten Minuteman II missiles. The Delta-01 tour is moderately strenuous and requires a quarter mile round trip walk to and from the Delta-01 compound. All tour participants must be able to climb two 15 foot ladders, walk, and stand unassisted.
Built for nuclear war, the control center features a small elevator and a tight underground space. To protect the historic facilities and to provide for visitor safety, each tour is limited to six participants. Advanced reservations are required for all tours.
All adult tour participants must be physically capable of climbing two 15 foot ladders unassisted. These ladders are permanently attached to the wall and are very sturdy.

Service Animals
Service animals are an exception to most pet restrictions and are allowed on trails and in public buildings. Service animals must be kept on a leash at all times. Service animals are not allowed on the elevator or down in the underground control center at Delta One, due to their inability to climb the egress ladders in the event of an emergency.
