History & Culture

In Platte County, you can walk in the footsteps of early pioneers in the morning, and settle back into modern convenience that night.

If you remember playing “The Oregon Trail,” you’ll get a thrill out of visiting the very trails that thousands of covered wagons rumbled across—and seeing firsthand the ruts their wheels left behind. No fording the river required! 

And of course, no trip through Platte County history is complete without a stop at Register Cliff, Wyoming’s own living Facebook predecessor.
