Two days of extremes: descend into the massive 816 Underground Nuclear Plant, hike the Wuling Grand Canyon on suspended walkways, then ride alpine meadows to the UNESCO Three Natural Bridges. Practical, geological, and historic — ideal for hikers who want bold scenery and context.
More ways to explore the area's outdoor wonders
You step into a hollow of stone and mist: limestone cliffs lift like cathedral walls, a river below hurls itself through a canyon, and an artificial city sleeps in the belly of the mountain. Over two days this itinerary stitches together raw karst geology, Cold War infrastructure, and highland meadows that open onto endless sky.
