Explore the Madison Area

Casey's General Store on Highway 34 offers propane fills and basic RV supplies, though selection stays pretty limited. For more comprehensive RV needs, you'll want to stock up in Sioux Falls before heading this direction.

The dump stations at RV parks typically open early but may close by 8 PM, so don't count on late-evening access. Call ahead if you're arriving after normal business hours, especially during off-season months when some facilities reduce their operating schedules.

Fresh water is available at most locations, but bringing your own drinking water makes sense since some wells in the area have mineral content that affects taste. Lake Herman State Park maintains the most reliable facilities if other options seem crowded.
