Fanjingshan, China’s newest UNESCO World Heritage site, is worth the climb. A sacred Buddhist site (48 temples once stood on the mountain), Fanjingshan rewards hikers with bizarre rock formations and above-the-clouds views of China’s Wuling mountain range. The steepest climb is to 7,664-foot Red Clouds Golden Summit, two temple-topped peaks linked by a bridge. You could skip the climb and ride the summit cable car, but hiking offers an up-close look at Fanjingshan’s rich biodiversity, which includes endemic and rare species, such as the gray snub-nosed monkey.
