About the beach

Grandes Rocques

Grandes Rocques, also known as Saline Bay, is a sandy beach framed and divided by prominent granite outcrops. The bay lies immediately north of Cobo and is a popular place for family visits, high-water swimming and west-coast sunsets.

Grandes Rocques Beach Kiosk sits beside the bay, with public toilets and free parking nearby. The main beach access beside the kiosk includes steps down to very soft sand and is not step-free.

Tide & the beach

At lower water, more sand and rocky foreshore are exposed. Around higher water the sea is closer to the beach entrance and the bay is popular with swimmers, but many rocks become partly or fully submerged. Enter the water carefully and do not use the predicted tide height as a measure of depth over individual rocks. Never dive or jump into unfamiliar water.
