Keelung Xianyan Cave

　　   Xianyan Cave is situated in Xian Cave Village, Zhongzheng District, northwest of Keelung. It is a natural sea-eroded cave, with the sea once right beside it. Nowadays, due to coastal uplift, it is more than 10 meters away from the sea. Legend has it that immortals once cultivated themselves here and ascended to heaven, hence the name "Xian Cave" (Immortal Cave).

　　   The area around Xian Cave features naturally formed, uniquely shaped rocks and stones, creating an eye-catching landscape. As you climb the steps, you will see the three characters “Xian Dong Yan” (Immortal Cave Rock) inscribed on a stele. Beside the stone staircase in front of the cave stands a grand and magnificent Buddha statue for worship. Inside Xian Cave, there are mainly the Main Cave, Right Cave, and Left Cave. The interior is quiet, dim, winding, and mysterious. On the stone walls on both sides of the main cave, there are many exquisitely carved Buddha statues and ink inscriptions. At the end, there is also a Buddha statue for people to pay homage to. On the right side is a small cave that is not easy to venture deep into, but incense can be burned and prayers offered outside the entrance. The left cave is completely dark, so visitors must bring their own flashlights to explore. The width and elevation of this cave vary, requiring visitors to crouch or sidestep at times to pass through. After about 80 meters, the view suddenly opens up.
