. Batu Caves – Malaysia (1/20)

Located just outside Kuala Lumpur, the Batu Caves system features a vast network of caves that run over 4 kilometers (2.5 miles) through limestone hills. The caves are of religious significance to Hindus, and a massive statue of Lord Murugan stands at the entrance. Though the caves are relatively small by international standards, their cultural significance makes them an important destination.
