Haji Ali Dargah, Mumbai
Concierge.com's insider take:
The windswept dome and minarets of the Haji Ali shrine, built in 1631, appear to float in the Arabian Sea when the tide is in; as the water recedes, a narrow walkway emerges between the mainland and shrine for believers to cross over. The mausoleum is open to anyone, and contains the tomb of Haji Ali, a merchant-saint who died while sailing toward Mecca, and whose body is said to have washed up on Mumbai's shore. The best time to visit the tomb is at dusk, when a raucous group of mystics and musicians assemble and perform devotional songs.
