Eight ways to experience Jersey’s giant tides

Enjoy the rise and fall of island tides with these must-try experiences.


Jersey’s not just an island. It’s a natural playground where one of the largest tidal ranges in the world changes the island’s landscape - almost doubling in size twice a day. Explore Jersey’s tides with activities in, on and around the rise and fall of the tide - just remember to stay safe and only walk out at low tide with an expert guide.


When Jersey’s tides drop, the warm beach rockpools are left teeming with life from tiny crabs and fish to colourful anemones. Stay still and keep quiet, and adventurous rockpoolers will be rewarded with glimpses of sea creatures at their feet. Try Grève de Lecq and Green Island at low tide for easy access rockpooling - just don’t venture too far out.


Explore secret islands

Keen to conquer your own deserted island? When the tide drops at Portelet beach, you can walk out to l’Île au Guerdain, a tiny grass-topped island and Martello tower in the centre of the bay. Known locally as ‘Janvrin’s Tomb’ after a returning sea captain with the plague was buried there, it’s an intriguing space to explore.


Walk an ancient causeway

Tread in the footsteps of history and take the causeway out to the 16th century Elizabeth Castle when it’s fully uncovered at low tide. Stay and enjoy exploring the fortress, and watch reenactors fire cannons and muskets.  If you’re returning at high tide, catch the Castle Ferry - an amphibious vehicle fondly known as a ‘Duck’ back to shore, it’s all part of the experience.


See food… and eat it

Head to Grouville Bay along the coastal road, and at extremely low tides you’ll see the rows of oyster beds uncovered by the sea - they’re the largest oyster beds in the British Isles. Take a closer look with a guided low water walk out to the oyster fishery and mussel beds with a local expert. Don’t fancy getting your feet wet? Look out for Jersey oysters at local restaurants around the island.


Pristine sandy beaches

Some of Jersey’s beaches are only fully revealed when the tide falls, leaving a crescent of smooth sand and shallow water ready to be explored. Plémont beach is at its most beautiful at a low tide, when clear swimming water, rockpools and hidden caves and waterfalls are all waiting to be discovered.     


Seymour Tower

Trekking across a low water wilderness to discover a historic tower nearly two miles offshore, now that’s a unique adventure. This 18th century tower stands in the middle of an internationally-recognised RAMSAR wetlands site - look out for tiny porcelain crabs, anemones and cushion stars on the way through this lunar low tide landscape. Note - only venture out with an expert guide.


See a lighthouse up close

Only revealed at low tide, walk the causeway out to La Corbière lighthouse to discover a landscape of secret beaches and rockpools. Keep an ear out - the tide races in extremely fast and an alarm warns visitors when it’s time to leave the causeway.




Take one wide stretch of sand at low tide, add a good westerly blowing in from the Atlantic and you’ve got the ingredients for an adrenalin-packed, high speed blokart ride on St. Ouen’s Bay. These go-kart style land yachts are steered like a bike and are easy to master after a short safety and technique tutorial.
