Corbiere causeway


The causeway to Corbiere Lighthouse covers on an incoming tide extremely quickly. If you are unsure about the tide and conditions, don’t take the risk! The distance between the lighthouse and shore is around 300m, so allow up to 10 minutes to cross the causeway.

In an Emergency, dial 999 and ask for the Coastguard

Warning Siren

There is a warning siren that sounds when the causeway is about to cover. If you hear the siren, you should immediately make your way back from the lighthouse via the causeway, as the tide will cover the causeway imminently. In an Emergency, dial 999 and ask for the Coastguard.

Tides and Causeway Calculator

Before you use the causeway, please check the tide times. There is a causeway access calculator that gives information on when the causeway at Corbiere, and other locations around the island, will be accessible.

If you get cut off

Don’t panic and put yourself at risk. If you are already at the Lighthouse when the causeway covers, remain there, find a safe area to wait and contact Jersey Coastguard immediately, dial 999 and ask for the Coastguard.
