WYO 24 is begins at US 14 in Carlile Junction (also known as Devils Tower Junction). From its western terminus, it travels in a north–south direction, although the route is signed east–west. It is mainly a two-lane highway from US 14 to near Devils Tower National Monument. When it gets to Devils Tower, it spawns a short spur, Wyoming Highway 110 (WYO 110). After passing by WYO 110, it curves northeast-southwest. The road reaches Hulett, where it intersects Wyoming Highway 112. In Hulett, WYO 24 is dubbed Main Street and A Street. Moving on, WYO 24 curves to the signed east–west orientation, but curves northwest-southeast. WYO 24 passes by some gulches, most notably Reservoir Gulch and Lucky Gulch. WYO 24 then turns south, then generally follows the east–west orientation. It then intersects Wyoming Highway 111 a short time later. There are no further major junctions and towns on the route, as WYO 24 crosses the state line and becomes SD 34.[citation needed]

In 2018, the speed limit on WYO 24 near Devils Tower was reduced from 65 miles per hour (105 km/h) to 45 mph (72 km/h) due to higher traffic volumes during peak travel seasons and the road's history of collisions.[2] The monument had its highest visitor count in 2021, which saw traffic jams from the entrance that slowed a section of WYO 24.[3]
