The incredible rhythm of the ocean’s changing tides is so powerful, it can cause entire landforms to submerge and reemerge with each ebb and flow. In fact, many places we consider islands are only surrounded by water mostof the time. Sometimes, they reattach to the mainland as the tide rolls out and ocean floor reappears to form a footpath or even a drivable road. When visiting these 11 “sometimes” islands, timing is everything, lest you be stranded out at sea when the waters rise again.
