Castle Rock Beach

Castle Rock Beach is a tiny, tucked-away gem near Clontarf — just 30 metres of sand sheltered from the open water, with a striking freestanding boulder sitting right in the shallows. You anchor off and swim in — the calm, protected conditions make it one of the nicer dips on the Spit. It's the kind of spot that feels like a secret even when you know about it.
