Haikou Immortal Cave

　　Haikou Immortal Cave is located in Rongtang Village, Shishan Town, and got its name from the legend of a Taoist priest who attained immortality inside the cave. The cave is divided into upper and lower sections. The lower section features a cave within a cave, and a sky beyond the sky, creating an utterly bewildering and awe-inspiring sight. Most parts of the cave are pitch dark, making it difficult to proceed without the aid of torches or flashlights to cautiously navigate ahead.

　　The walls are adorned with various types of stalactites and stalagmites, hanging and clinging as if about to fall but never quite doing so—truly a breathtaking spectacle. The cave is remarkable not only for its rocks but also for its water. At any time, one can hear the crisp sound of dripping water, which produces different tones as it falls on rocks of varying textures, creating a wonderfully melodious symphony. The upper section of the Immortal Cave has split into dozens of lava tunnels due to multiple collapses in the cave ceiling, hence it is also known as the "Seventy-Two Caves."

　　These caves vary in shape—some resemble interconnected spider webs; some look like spacious underground restaurants; others resemble peculiar ancient castle palaces. Sunlight streams in through skylights formed by cave collapses, illuminating the otherwise dark interior and revealing spectacular and mystical sights.
