Cocklebiddy Beach is a stunning, remote white-sand beach on the edge of the Nullarbor Plain where the towering limestone cliffs of the Great Australian Bight meet the Southern Ocean. Accessed via a rugged 4WD track behind Cocklebiddy Roadhouse, this wild and isolated spot near Twilight Cove offers powder-fine squeaky sand, dramatic cliff-backed scenery, and the sensation of true wilderness. On calm days, the crystal-clear waters provide excellent snorkeling over sandy shallows and rocky reef gutters, with minimal crowds—often none at all. It's an off-the-beaten-path gem for adventurous snorkelers seeking pristine solitude.

Moderate risk: 4WD track hazards
The access track from Cocklebiddy Roadhouse includes a steep, rutted descent down the scarp and soft sand dunes. High-clearance 4WD with low tyre pressure is essential. Getting bogged or damaged is a real risk.
Moderate risk: Strong winds & swell
The Great Australian Bight coast is exposed to strong prevailing winds and large Southern Ocean swells, especially from spring through autumn. Rough conditions can create dangerous surf and poor snorkeling visibility.
Low risk: Weed & surge in rough conditions
During windy periods, kelp and seaweed accumulate in the shallows, and surge can make swimming and snorkeling difficult. Calm days are essential for safe entry.
Low risk: Stinging jellyfish & bluebottles
Bluebottles (Portuguese man o' war) and occasional box jellyfish can drift into the Bight with onshore winds, particularly during summer months. Stings can be painful and require immediate treatment.
