Carved over millions of years, the steep cliffs and deep ravines of this karst geological wonder allow travelers to experience the thrill of journeying underground.

Spanning 5km with 2km open to visitors, the valley comprises the entrance fissure, midway tunnel, and exit gorge plummeting 200-500m down. Lush primal forest, cascading waterfalls, and magnificent rock faces await within.

Ride the elevator 80m below the surface, emerging to behold majestic waterfalls. Visit from Wulong County or connect from Tiansheng Bridge. Shut
