Minuteman Missile National Historic Site

Minuteman Missile National Historic Site is easy to miss and hard to forget. Tucked beside Interstate 90 near Philip, South Dakota, it preserves two pieces of a once-vast network of nuclear missile sites that stood on constant alert during the Cold War. The Delta-09 missile silo lets visitors look through glass at a Minuteman II missile in its underground launch tube. The Delta-01 Launch Control Facility, which once controlled ten missiles, is visited by walking to the gate of the compound and, with a ticket, joining a ranger-led tour of the underground control center. The National Park Service says the tour lasts forty-five minutes, with a quarter-mile round-trip walk, and is limited to six participants, so tickets sell out quickly. Visiting the site is a good companion to the Badlands, since the two share the same interstate corridor. The history is sobering and thoroughly told, and it gives the prairie a different meaning once you see what lay beneath it.

Start at the visitor center, which sits close to the interstate and introduces the story of the Minuteman program, the crews who served in the launch centers and the strategic thinking of the period. From there, the Delta-09 silo is a short drive away, and the view into the shaft is the part that most visitors remember.

The Delta-01 facility is a further stop, and its compound includes the above-ground building and the entry to the underground capsule. The park also offers audio tours at both sites and virtual tours online, which are helpful when you cannot get a ticket.

The ranger-led Delta-01 tour needs careful planning. Tickets are reserved through Recreation.gov up to 30 days ahead, and the park says tours fill quickly. In the warmer months the tours run in the morning, and in the cooler months they run in the afternoon on certain days, so check the current schedule.

Children must be at least 40 inches tall and six years old, and able to climb the ladder unassisted, which rules out toddlers and anyone who cannot manage the steps. Arrive early at the gate, wear sensible shoes and expect a short but vivid look at a cramped underground room.

Combine the site with a Badlands day. Minuteman sits not far from the park's northeast entrance, so many visitors stop on the way in or out, or pair it with Wall Drug on the return to Rapid City. If you are traveling with a guide, a private tour that names Minuteman is the simplest way to fit it in; the guided Badlands and Minuteman tour on this page does exactly that.

Check hours and seasons on the National Park Service website before you go, because the visitor center and silos follow their own schedules, and mobile coverage along the corridor can be patchy.
