What: A mosque and dargah (tomb) considered to be an excellent example of Indo-Islamic architecture that is visited by thousands of devotees a week.
Getting there: A narrow walkway, 500 metres long, that is only passable during low tide and particularly perilous during the monsoon season.
The legend: The dargah was built after the body of a wealthy Muslim merchant washed up on shore after his coffin was cast into the Arabian Sea. He’d injured the earth, apparently, after jabbing his finger into the soil and discovering oil.

Jindo Miracle Sea Road Festival (Visit Korea)
Where: The stretch of water between the island of Jindo and the mainland in South Korea.
What: The Jindo Miracle Sea Road Festival, celebrating a natural causeway that only appears twice a year, linking the island of Jindo with the mainland.
Getting there: A 2 mile-long causeway, 120 feet wide, that only appears during extremely low tides, and even then, is only walkable for an hour. Be warned: Half a million people turn up to do the walk each year.
Legend: When tigers invaded Jindo, a girl called Bbong was left behind. She prayed to Yongwang to reunite her with her family and he answered them by parting the sea. Each spring, the miracle recreates itself.
Mont St Michel (Shutterstock.com)
Where: At the mouth of the Couesnon River Normandy, France.
What: Arguably the world’s most photographed tidally-challenged attraction, the structural composition of the town exemplifies the feudal society that constructed it: on top, God, the abbey and monastery; below, the great halls; then stores and housing; and at the bottom, outside the walls, houses for fishermen and farmers.
Getting there: A causeway, revealed at low tide. Avoid the temptation to cut across the mudflats. Many a medieval pilgrim lost their lives that way, earning the island the nickname of ‘St. Michael in peril of the sea.’
Legend: The Mont remained unconquered during the Hundred Years' War when a small garrison fended off a full attack by the English in 1433Shutterstock.com)
