A lovely secluded harbour beach at Mosman in Sydney with a 4.6 rating across 95 reviews.
Practical details
Why it's worth checking out
Castle Rock Beach sits on Sydney Harbour in the Mosman area of Sydney's Lower North Shore. A strong 4.6 rating from 95 reviews reflects its standing as a much-loved spot.
The appeal is a secluded, natural harbour beach — a lovely, tucked-away stretch of sand reached by a bush track through Sydney Harbour National Park, a genuine favourite for a quieter swim, a paddle or simply soaking up the harbour scenery away from the crowds. It's a lovely, largely unspoilt spot.
Harbour beaches have changing conditions, tides and limited facilities, and access involves a walk, so check current details and any advisories before you go. Bring sun protection, water and your swimmers, and take care in and around the water.
