Sanjay Gandhi National Park

This guide to Sanjay Gandhi National Park in Mumbai starts with a simple fact: somewhere in the trees around you right now is a wild leopard, one of more than fifty living inside the boundaries of one of the world's densest cities. You'll hear how the forest's only natural edge is a creek to the north, with concrete pressing in everywhere else, and then travel deeper to the Kanheri Caves, where Buddhist monks spent nearly a thousand years hand-carving one hundred and nine rooms into black basalt. It also traces the reservoirs hidden in these hills that still supply much of Mumbai's drinking water.
