One of the most extraordinary religious festivals in the world. Tamil Hindu devotees carry kavadi — elaborate metal structures pierced through their skin as acts of devotion — in a procession from Sri Mahamariamman Temple in central KL to the Batu Caves, 15km away. The Batu Caves themselves, a series of Hindu temples inside limestone caverns reached by 272 rainbow-coloured steps, form the dramatic finale. Over a million people participate or witness the procession. The devotees, in trance states, are believed to feel no pain. It is simultaneously terrifying and deeply moving.
The procession begins before dawn — arriving at 4–5am puts you at the start. The Batu Caves steps by midday are crushingly crowded. Respectful, fully-covered dress is required. Photography is acceptable but ask before photographing devotees at close range.
