For a big city, Salt Lake is rather small, and has a fairly short history. However, its petite size and youth do not make it boring. Rather, Salt Lake City, boasts an interesting and unique past that it proudly displays. And despite the relatively modest size of its downtown, it is rich with historic and cultural sights. And given the city's impressive and distinctive natural surroundings, much of the area's sightseeing is found outside of the city limits.
Those wishing to check out the urban sights would be well served to head downtown. In the very heart of it all, you'll find the number-one sightseeing attraction in the entire valley: Temple Square. Within the grounds are the the Salt Lake Mormon Temple itself, the Tabernacle and its famous choir, and numerous other structures and monuments. Immediately outside of the Square are a number of LDS outposts, including the Family History Library and the LDS Conference Center.
Northeast of Temple Square you can find other historic structures like the impressive Cathedral of the Madeline, the historic First Presbyterian Church, and the Utah Governor's Mansion – where the governor and his family actually live today.
If you have the means to leave town, consider heading northwest to Antelope Island State Park. Occupying the largest island in the Great Salt Lake, this island features open grasslands and mountains in the middle of this vast body of water. If you travel west on I-80, you'll wind up at the Bonneville Salt Flats, an incredibly empty stretch of utterly flat land on which all the modern world land speed records have been set.
Whether you're into history, religion, or bizarre landscapes, you'll find the sightseeing in and around Salt Lake City to be as diverse as it is interesting.
