The wonders of nature are many, and among the most curious are tidal islands – landforms that are only accessible when the tide is out, whether by foot, vehicle, or causeway, but become entirely isolated when the tide comes in. Tidal islands are the allure of isolation and legend; they seem to emerge and submerge with the swell of the sea, resurfacing only to tell adventure tales.
Internationally, there are a variety of beautiful tidal islands, each with a story, natural wonders and a touch of mystique. So, in this blog post, we will dig deeper into 8 of the most interesting tidal islands in the world, that will pique the interest of travelers, history lovers, and nature lovers alike.
What is a Tidal Island?
A tidal island is a landmass that can be reached during low tide, but only by crossing a natural or man-made causeway. When the tide rises these paths go underwater, temporarily cutting off the island from the rest of the world until the next low tide.
Tidal islands are surreal: step across a sea bed, time travel and get steeped in coastal culture, wildlife and ancient tales.

Mont Saint-Michel is arguably the most famous of all the tidal islands in the world. A UNESCO World Heritage site, this 8th-century abbey and village sit on a rocky promontory off the coast of Normandy in France, appearing to rise from the tidal flats below like something from a storybook castle.
Visitors can walk across the sand at low tide or take the high causeway. The mount is completely surrounded by the sea at high tide, making it appear almost like an island fortress.
Highlights:
- 11th-century abbey and gothic church

They are solitary, adventuresome and full of stories, like the land itself as they only appear and disappear with the tides. From the ancient spirituality of Lindisfarne, the romantic grandeur of Mont Saint-Michel, and the natural wonder of the Jindo Sea Road, they each offer a memorable tale of their own.
So, if you are planning your next trip to the coast, tie it to the tides. And if you do, you may just be walking on the floor of the ocean to uncover a hidden world that disappears within a few hours.
