Free shuttle from the SLC Airport to downtown, including a small tour around the downtown. The shuttle is operated by the Temple Square folks – Very nice people, they will explain about the buildings downtown and the history of SLC without any religious pressure.

The downtown has many large buildings, some of them amazing feats of architecture (The Conference Center hosts 21,000 and is built without any pillar), is open, and feels lively, although everyone is dressed up (probably working at the numerous Mormon missions nearby).

There are many free tours. Do take the 40-minute tour of the Conference Center building, see the Auditorium, and the view from the gardens on top.
