My family and I took a day trip to the museum from Phoenix on a Saturday in early June. Easy drive with our 15 year old son. The tour starts with a short and very informative film to introduce the background of missile silos in the U.S. The film was extremely well done and really introduced what we were about to see and put it into context. Folks 5'10" and over are required to wear a hard hat into the actual missile site. Very low ceilings in some areas, so tall folks will need some protection. There is an elevator for anyone not able to take the 5 levels of stairs in or out of the silo. I'm not in great shape, but founf the stairs in and out very manageable. Our group consisted of about 20 adult-sized folks and sometimes it was a tight squeeze and somewhat claustrophobic, but if that bothers you, I suggest you hang to the back of your group when the guide stops to point out features of the museum. We visited the control room, where the guide walked through the actual procedure that would have been followed if the missile ever had to be fired. Really interesting stuff! We walked through the tunnel that connects the control room to the actual silo and learned how the unique design of the building protected it from attacks or earthquakes...I'll tease it and say part of the structure is actually suspended on multiple HUGE springs! the missile is easily visible and my son got some great pics. Tourists can't walk out on the platforms that surround the missile, but it's set up so you get a good view of the missile and the silo. Bob was our tour guide and did an outstanding job with the tour...he was very interesting and laid out some wonderful facts about this particular site! One of the best things about the museum is that it does not promote war at all, but presents it as a very awesome responsibility and reminds citizens that nuclear war is really self-destruction. Highly recommend a visit!
