Mumbai
Take a ferry to Elephanta Island (9 km from Gateway of India) — a UNESCO World Heritage Site containing extraordinary 5th–8th century rock-cut cave temples dedicated to Shiva. The massive Trimurti (Shiva with three faces — Creator, Preserver, Destroyer) sculpture in Cave 1 is considered one of Indian sculpture's supreme masterpieces.
The caves are closed on Mondays. The mini-toy train at the ferry point takes you up the hill (₹15). Hire an ASI guide at the entrance for the best Shaiva iconography explanations.
