New South Wales has plenty of hidden swim spots (you can read all about them here), but the beaches nestled in Sydney’s harbour – that only locals know about – are some of the most beautiful beaches in Down Under. 

Cue: Castle Rock Beach. This little-known swim spot is a sweet reward for those who take on the Spit Bridge to Manly Walk. Hidden among the cliffs between Clontarf and Grotto Point, the tiny cove is a welcomed respite for the hikers in the warmer months. 

Whenever the picturesque cove makes its way onto TikTok it goes viral, and for good reason. To put it simply, Castle Rock Beach is stunning. Crystal blue waters are surrounded by native bushland and freestanding boulders and rocks.

To access the beach, saltwater seekers will need to descend worn stairs from Oglivy Road. Once you reach the shores there’s hundreds of metres of reef and beach so there’s plenty of space for visitors, without feeling overcrowded.

Come summer, it’s often a popular place for boats and yachts to pull into, which is reminiscent of any European beach during peak season. While located in Sydney’s harbour Castle Rock Beach looks like it could be better placed in Greece or Italy. 

Thanks to its isolated location, even on a scorching hot summer day Castle Rock Beach doesn’t get too busy. But do come prepared with drinks and snacks. There are no facilities here so you’ll have to BYO, just make sure to take your rubbish with you when you leave.
