About the beach

Grandes Rocques

Grandes Rocques (also known as Saline Bay) combines sandy sections with large granite formations. At low water more of the rocky shoreline is exposed; as the sea rises, some rocks become submerged and harder to see.

It sits right beside Cobo, and it’s a recognised west-coast sunset spot. Higher water is popular with local swimmers, but submerged rocks are a real consideration, so check the water carefully and don’t rely on the predicted height alone to judge depth.

Tide & the beach

Higher water is the popular swimming state, but rocks that are visible at low tide disappear as the sea rises. Avoid diving into unfamiliar areas.
