Road becomes GA 101. After approximately 1 mile, the road ends at a three-way intersection. Turn right onto Harlan Lane. Travel on Harlan Lane for exactly 2 miles. Turn left onto Tapley Road.
Observatory is on right side of road.
Look for a stone wall with an iron wagon wheel gate. The observatory driveway is about 100 feet before that stone wall on the right. Observatory has four buildings. Two of the buildings are white cinder block, the third building is a dome, and the fourth a large white wooden building. Exit interstate at exit 98 which is highway 11.
