Sri Pada, or Adam’s Peak, is a 2,234m-high mountain which is sacred to all four main religious groups in Sri Lanka – Buddhists, Hindus, Muslims and Christians, all of whom variously claim the giant footprint at the top to be that of Lord Buddha, God Shiva, Adam or St. Thomas (the Christian apostle who preached in South India. Climbing the mountain is a popular pilgrimage, and a steady trickle of travellers join devotees between December and April to attempt the ascent. The climb is best started at about 2am – after a 3.5 hour hike, you will reach the summit and witness one of the most glorious sunrises in Asia. During pilgrimage season, strip lights and rudimentary stalls light the way to help keep you going all the way to the top. For many, this is a moving highlight of their stay in Sri Lanka and it is certainly one of the most awe-inspiring things to do in the island.
