Two of Mumbai's most religious sites stand almost back to back – the Hindu Mahalaxmi Temple dedicated to the goddess of wealth, Laxmi, and the mausoleum of Haji Ali Bakhtari, a Muslim mystic. Haji Ali lies on a tiny island joined by a narrow causeway to the mainland, accessible only during low tide, an exotic sight. Don't miss the juice shops at the entrance to the causeway. The area around Mumbai Central station offers cheap accommodation too.
