Less than 120 km. If you drive, the best way is to take Hetoudian Expressway in the northwest of Laiyang, Yantai Expressway, 50 kilometers to Qixia North (Songshan) and 50 kilometers to Penglai. Less than 5 kilometers is a broken road, and the rest are good roads. This line is a bus route from Qingdao to Penglai, which is much better than the bus route from Laiyang to Penglai.
