A bush-encircled slice of heaven you need to visit before summer ends.
Australia is hardly short on spectacular, unknown beaches – many scattered across far-flung corners of the coastline – but Castle Rock Beach proves you don’t need to venture into the wilderness to stumble upon something extraordinary. Tucked into a pocket of Sydney’s Clontarf just south of Manly, this pint-sized cove is less than 30 minutes by car from the CBD’s glossy buzz.
Accessible only by walking down a series of worn steps, the postcard-worthy bay is just 30 metres long and blissfully sheltered. It’s little wonder locals and in-the-know Sydneysiders have long kept their lips tightly sealed. The harbour beach is cradled by tall sandstone slopes thick with native bushland, plunging to where shelves of shortbread-hued sand fade into ultra-clear shallows. On sunny days, bronzed bodies scatter the sand and stand-up paddleboarders glide past shiny mini-yachts anchored for the afternoon.

The calm waters are ideal for swimming, snorkelling or catching a sorbet-tinged sunset. But what truly makes Castle Rock Beach unique is that it not only has several large free-standing boulders, but also its own little waterfall. The cascade is about four or five metres tall and flows directly onto the sand after decent rainfall.

Be aware that the beach doesn’t have any facilities, shops or toilets, so remember to bring your own water and food. But that’s precisely the beauty of Castle Rock Beach – it’s secluded, quiet and unspoiled by man-made development.
