Wow! This is an extremely scenic beach & great thing to do in Sydney.
The walk along the promenade is flat, easy & very enjoyable. Old large trees offer sporadic protection from the sun along the walk. There are large grassy areas that would be awesome for a bbq or picnic.
Take the quaint old bridge across to Rocky Point Island for a great view into Sydney Harbour. This area is also very popular for picnics, the view of Balmoral either side is really nice.
The Rotunda & Billy (Dog Statue) are also worth a look.
Swimming conditions are usually very safe with little or no swell. Balmoral Baths is popular with youngsters jumping off the boardwalk into the water.
If you have not been here make the effort to visit.
