This is one of 30 “sea-night eyes” operating around the waters territory of Vietnam. The lighthouse was built in the late 19th century. To climb the lighthouse, tourists have to get over the steep bends, then climb 72 stairs to reach the top of the lighthouse. From here, you could comfortably take in the panoramic views of Co To island, from the dreamlike beautiful beach town, green trees, to simple but peaceful roofs.
