The 'Wild Boar Trench' name originates from a local legend about a wild boar that purportedly inhabited the cave area.
The trench walls are primarily composed of elevated coral reef limestone, indicating the island was once submerged.
The narrow path inside the trench creates a natural wind tunnel, often remaining cooler than the surrounding island areas.
It is one of the few places on Xiaoliuqiu where distinct geological faulting is clearly visible from a walking path.
Wild Boar Trench Trail is a coral limestone canyon formation located on the western coast of Liuqiu Island. The trail follows a narrow, steep-walled crevice created by tectonic uplift and subsequent erosion. It is part of the island's unique karst topography, characterized by jagged coral rock faces. The path is integrated into the larger landscape through a series of wooden walkways and observation decks. Lush tropical vegetation, including banyan trees and ferns, grows within the sheltered microclimate of the trench. The site serves as a prime example of the geological history of the Pingtung offshore islands. Visitors can observe the transition from the interior forest to the coastal cliffside environment.
The narrow section where the sunlight filters through the canopy onto the vertical rock faces.
Wear shoes with good traction as the coral rock and wooden planks can become slippery in humid conditions.
Apply mosquito repellent before entering the trail, as the shaded, damp environment is a breeding ground for insects.
Keep a safe distance from the edges of the coral cliffs to avoid loose debris.
Do not attempt to climb the coral walls, as the rock is extremely sharp and brittle.
Stay on marked trails to protect the fragile coral limestone ecosystem and avoid damaging endemic plant life.
