The Kanheri Caves come to life during India's monsoon season, when pools overflow into waterfalls and budding exotic greenery takes over Sanjay Gandhi National Park. The 109 Buddhist chambers were sculpted from an outcropping of basalt in ancient India (400 BC, near the height of ancient Greek civilization). The monk's chambers were kept simple, as the site was for pilgrimages and learning; however, there are fascinating traces of canal infrastructure, intricate wood carvings, and statues of Buddha. Visitors can explore the park and caves with relative ease. The trail is about three miles long, so bring comfortable walking shoes.
