Watu Ulo is one of the tourist sites which lies on the Indonesian ocean. There is beautiful scenery at this site and it is the perfect place to enjoy the sea. It is called "Watu Ulo" by the natives because they believe that in the past there was a snake who was becoming a spirit. After becoming a spirit, it became a stone resembling a snake, sticking into the sea with its body lying on the land. During the Japanese occupation, the Japanese soldiers made fortresses which were used for fortifying against the attacking enemies and now some of the fortresses have become tourist sites. Beside the Japanese fortress, there is also a bat cave inhabited by thousands of bats. The visitors can cross the sandy shore to get to the cave. The lonely cave is often used for meditation by visitors. However tourists should remember that the cave is 100m in depth. To get there, the visitors can use public transportation or hire a rental car. The journey takes approximately 30 minutes from the downtown of Jember.
