The Leshan Giant Buddha, 130 km south of Chengdu, is the world's largest stone Buddha statue at 71 metres tall. Carved from a cliff face at the confluence of three rivers during the Tang dynasty, it is a UNESCO World Heritage Site and one of the most impressive Buddhist monuments in Asia.
The best view is from the river — take a boat tour from Leshan town for the full frontal view. You can also descend the cliff stairs (very steep, very crowded in peak season) to stand at the Buddha's feet. High-speed trains from Chengdu East Station reach Leshan in about 40 minutes. Combine with Emei Shan (the sacred Buddhist mountain 30 km away) for a proper two-day excursion.
