There are a number of tours that leave from the KSC Visitors Complex, they include (when last I checked):

• The KSC Bus Tour which is included with admission and allows visitors to spend as much time as desired at the Apollo/Saturn V Centre before returning to Visitor Complex.
• The KSC Up-Close Launch Control Centre Tour (extra cost) includes a visit to Firing Room 4, one of the four firing rooms and the one from which all 21 shuttle launches since 2006 were controlled and other behind the scenes areas.
• KSC Up-Close Cape Canaveral: Then & Now Tour (extra cost - do check as it is frequently withdrawn) takes you into the Cape Canaveral Air Force Station and Patrick AFB to visits a number of the historic places where America’s space program was born such as Launch Complex 26 – the launch site of Explorer 1.

I strongly recommend the Then and Now tour as it gives a real feel for the scope of the Cape Canaveral area and just how little of it is now in use.

The following pages give a look at some of the areas the tour takes in.  I was particularly lucky as the guide when I took the tour was a veteran of Patrick AFB and had been there in the early days when, as he put it, they were firing something off every day!

On the day I took the tour all the active Launch Complex were in use, the two SRB recovery ships were in harbour, the two SRB were in wash down and a barge with a Shuttle External Tank had arrived from the Michoud Assembly Facility.  Our tour  guide joked that we should have been charges extra.

I found a web site that provided useful information on every launch complex built at Cape Canaveral, it is the Air Force Space and Missile Museum site.
