Longzhua Mountain is located at the northern end of Daheishan Island, 5 minutes' drive from the pier. It is composed of 5 cliffs facing the sea and gullies. Its cliffs and broken arms extend to the sea. The mountain is steep, the boulders are mysterious, and the reefs and caves are mysterious. It is named because it looks like a dragon claw diving into the sea. There is an unknown "immortal road" on the cliff of Longzhua Mountain. It is about 1,500 meters long and only 1 meter wide. It is embedded in the quartzite cliff. Legend has it that it is the trace left by the Eight Immortals passing through here. There is a sea cave on the west side. The cave is deep and lightless. The width is only two people standing side by side, but it is difficult to touch the top. Legend has it that it was the resting place of the Eight Immortals when they crossed the sea. It is named "Juxian Cave" and is the only existing sea cave in China. There is a rare "stone building" at the westernmost end of the mountain. The four walls are all at 90 degrees to the sea surface. There is a natural window on the top. Sunrise, dusk and the stone building present a changing glow. Through the stone building, you can see the ever-changing unique scenery, so it is called the "Eye of Long Island".
