Traveling to Interior by RV

Getting to Interior with your RV is pretty straightforward, though you'll want to plan for prairie winds and long stretches between services. Highway 44 is your main route into town, connecting west to Scenic and the Badlands Loop Road, or east toward Mission and eventually Highway 83. From Interstate 90, take Exit 131 at Kadoka and head south on Highway 73 for about 20 miles, then west on Highway 44 for another 10 miles to reach Interior.

The roads around Interior are well-maintained and RV-friendly, with good sight lines across the open prairie. You won't encounter low bridges or weight restrictions on the main routes, but be prepared for significant crosswinds that are common across this part of South Dakota. Highway 44 through town is wide enough for big rigs, and most businesses have adequate parking areas.

Overnight parking options are limited to the campgrounds and RV parks in town, as there's no Walmart or major truck stops with overnight policies. The closest rest area is back on I-90, so plan accordingly if you need a quick stop. Cell service can be spotty once you get away from the main highway, so download offline maps before heading into the more remote areas of the Badlands.

Seasonal considerations include potential snow and ice from November through March, though the main highways are typically cleared quickly. Summer brings the heaviest RV traffic, so expect longer waits at dump stations during peak afternoon hours when folks are checking out of campgrounds.
