From Rapid City

Follow Highway 16 (Mt Rushmore Rd) south through Hill City and on to the Crazy Horse Memorial. One mile past Crazy Horse is the intersection for the tourist attraction called "Heritage Village". Turn right/west onto Medicine Mtn Road (We have a green sign at the intersection). Follow this gravel road for 4 miles (Go left at the Y in the road). Watch for the Lutherans Outdoors sign. Atlantic Mountain Ranch's driveway is on the right.
