Which English bay is the UK’s largest expanse of intertidal mudflats and sand? Morecambe Bay is.

Morecambe Bay is a broad inlet of the Irish Sea on England’s northwest coast, bordered mainly by Cumbria and Lancashire. Its extensive intertidal mudflats and sand make it the largest such area in the United Kingdom. Several rivers drain into the bay, including the Leven, Kent, Keer, Lune and Wyre, creating estuaries and distinctive peninsulas.

The bay’s landscape was shaped partly by glacial meltwater. Its sandflats preserve remnants of an ancient outwash plain formed as the last ice age ended, while changing tides continue to reshape the coast. The area supports rich wildlife and is protected through designations including a Special Area of Conservation, Special Protection Area and Site of Special Scientific Interest.

Morecambe Bay is also famous for dangerous quicksand and fast-moving tides. For centuries, appointed guides helped travelers cross the sands. The bay is not the Wash, another major English tidal inlet, nor Liverpool Bay, which lies farther south in the Irish Sea.
