Natrona County, Wyoming

Natrona County sits right in the middle of Wyoming. It’s home to Casper, the state’s second-largest city. The county has a bit of everything, including mountains, prairies, and the North Platte River running through it.
Oil and gas are big here. So is ranching. Locals love the outdoors. The county’s history is tied to the Old West and the oil boom.
Casper Mountain looms over the city, offering skiing in winter and trails in summer. It’s not all nature though. The county has museums, shops, and a growing food scene. People here are friendly, with a strong sense of community.

TRANSPORTATION MAP
Natrona County Road Map
Casper is a hub, so several highways meet here. Interstate 25 cuts through, linking the county to both the north and east. But smaller routes head west like U.S. Highway 20. The interstate is fast, many scenic roads are worth the slower pace.

SATELLITE IMAGERY

At first glance, you’ll think Natrona County looks pretty bare. The majority is. But one spot to look at is the city of Casper in the east. But zoom out, and rocky terrain quickly takes over. Dry riverbeds, reservoirs, and barren ridges stand out the most here.
