Grève de Lecq, Sandy beach on the northern coast of Jersey, Channel Islands.

Grève de Lecq is a sandy beach on Jersey's north-west coast, about 10 km from Saint Helier, set between high cliffs with rocky outcrops at either end. The bay opens to the north and its sand and rock are exposed at low tide.

Grève de Lecq lies on Jersey's north-west coast, about 10 km from Saint Helier. The bay was fortified by German forces during the Occupation of the Channel Islands in World War II, not by the Allies; concrete bunkers and observation posts were built into the surrounding cliffs. Remnants of this Atlantic Wall defences remain visible in the headlands above the beach.

The name Grève de Lecq comes from Jèrriais: grève means a sandy shore, and Lecq refers to a rock in the bay. The beach is a tidal one, so its sand and rock pools appear and disappear with the tide, and the bay has long been a landing point on Jersey's north coast.

The beach has restrooms, showers, cafes, and large parking. Lifeguards are on duty during summer months, and planning extra time helps if you want to explore the rocky areas.

A large cave system runs through the eastern headland, and visitors can walk through the rock formation at low tide. These caves formed through natural erosion and offer an adventure for those watching the tide.
