After seeing the monuments, you can feel the ingenious work of nature. The columnar basalt listed by the large scorpion leaves is very spectacular. Because of the lack of time, I didn't go to Xiyu Xitai. This is a concave ancient fort. Interested friends may wish to see it. The last stop of the Northern Ring Line: Xiyu Lighthouse, also known as Yuweng Island Lighthouse, is the oldest lighthouse in Taiwan. This is a place full of literary atmosphere. I used to see the lighthouse every close distance. After I met it, I decided to see the lighthouses around the world. I think watching the sunset next to the lighthouse should be very romantic.
