What are the specific tourist routes from Beijing to Yantai Weihai for three days?

You can take the train when you have plenty of time, and you can go directly to Penglai or Weihai when time is tight. The railway station is close to the coach station and Ma Bei Road Station. If you fly, you can take the airport bus or take a taxi to the station, which takes about 20 minutes from the airport to the station.

There is nothing interesting in Weihai. You can go to Liu Gongdao, Rongcheng Chengshantou, Xixiakou and Shidao.

Penglai is mainly Penglai Pavilion, Polar Ocean World and Sanxian Mountain Scenic Area. When you have enough time, you can go to Long Island by boat.

Yantai to Weihai 1 hour, Penglai 50 minutes.
