The Pony Express is but one of the routes you can follow. The Utah guide allows you to follow the trail the Donner-Reed party took. See what they encountered and try to imagine driving the route with wagons and oxen. They had no good maps and had to break their own path on their trip. Follow the route to the desert and think about how the travelers must have felt when they saw that huge area to cross with no water in sight. Visit Donner Springs which lies at the bottom of Pilots Peak. There are many things to see along the way and the guide gives specific directions to all of it!
You can also follow Brigham Young's trail, see the trail the first emigrant family took which later became the Oregon Trail and much more. Along with directions, the guides also offer a bit of history about the people who first used these trails. They touch on what it was like for the emigrants to come in contact with Native Americans and what took place. These guides are full of information and are perfect for planning a trip west or even as a companion to take along!
