Follow the foreshore path north of Napier Street and look down towards Peters Pool, the smaller beach pocket below the path.
Peters Pool sits along the narrower stretch of beach north of Cottesloe's main foreshore. Offshore reef helps shelter the water from some of the open-ocean energy, creating the “pool” that gives this spot its name. The Town identifies the area primarily for swimming and walking, while Tourism Australia highlights it as one of Cottesloe's snorkelling spots.
On a calm day, bring a mask and look across the reef rather than expecting a bare sandy bottom. This is living coastal habitat, so enjoy whatever marine life happens to be around without touching or disturbing the reef. Conditions still change with swell, wind and tide, so the word “pool” isn't a guarantee of calm water.
The beach is reached from the coastal path, with several access points along this stretch. It also makes a nice pause on the walk between Cottesloe's main beach and North Cott - small enough to miss if you're hurrying, but quite different once you know what you're looking at.
