Salmon Haul Bay, Cronulla 

Situated on the edge of Port Hacking River, with sweeping views across to Bundeena and the Royal National Park, Salmon Haul Reserve is a hidden gem that feels like a private coastal retreat. Located at the end of the Cronulla Esplanade Walk, past Bass and Flinders Point, this spot is a dream spot for underwater explorers. With calm waters perfect for snorkelling, scuba diving, and fishing all without the crowds. Whether you're chasing marine life or a peaceful afternoon sprawled out on the rocks, Salmon Haul delivers that picture-perfect escape. 

Resolute Beach, Ku-ring-gai Chase National Park 

If you're craving a beach that feels like a secret whispered by the wild, Resolute Beach is it. Tucked deep within Ku-ring-gai Chase National Park, this secluded stretch of gold sand is pure coastal fantasy, fringed by bush and offering uninterrupted views across Pittwater to the iconic Barrenjoey Headland. Getting there is part of the magic: either paddle in by boat or take the scenic 2km bushwalk along the Resolute Track, where ancient Aboriginal rock art and lush trails set the tone for the escape ahead. At the nearby picnic area, fire up a barbecue under the canopy and soak in the sounds of nature before descending to your own private slice of paradise.  

Athol Beach, Mosman

Tucked beneath the lush headlands of Mosman, Athol Beach is a secluded harbour sanctuary that whispers luxury and tranquillity. With its west-facing shoreline, this hidden gem offers uninterrupted views of Sydney’s glittering skyline and the iconic Harbour Bridge— best enjoyed as the sun dips low and the water turns to gold. Accessible only via the scenic Bradleys Head Walking Trail or through the elegant grounds of Athol Hall, a beautifully restored heritage estate, this beach feels like a secret reserved for those in the know. Quiet, intimate, and impossibly photogenic, Athol Beach is where nature meets understated glamour. 

Milk beach, Vaucluse

Positioned at the edge of Hermit Bay within Sydney Harbour National Park, Milk Beach offers a rare blend of seclusion and sophistication. Surrounded by the heritage-listed Strickland House and framed by sweeping views of Sydney’s skyline and Harbour Bridge, this intimate beach feels effortlessly exclusive. Arrive by boat, public transport, or secure one of the few off-street parking spots and you’ll discover a tranquil haven perfect for snorkelling, fishing, or a sun-drenched picnic beneath the awning. Stroll along the Hermitage Foreshore and let the harbour breeze guide you to one of Sydney’s most photogenic secrets. 

Oatley Park, Oatley  

Combine a swim with a bush walk at Oatley Park, a 30-minute drive from the city centre in the leafy southern suburb of Oatley, near Hurstville. Here the 45-hectare bushland reserve hums with cockatoos and other birds drawn to the native flowers and trees, while the paved and unpaved walks through the bush offer lovely views of the Georges River. Head to Oatley Park Castle, a quirky sandstone lookout (complete with a solid sandstone parapet) built during the Great Depression, and you’ll see a sandy beach through the trees. This is Oatley Baths, a 200m-long netted swimming enclosure with change rooms and picnic tables. Swim a few long laps of the enclosure, or simply laze on the pontoon and watch the cockatoos fly overhead. 

Congwong Beach, La Perouse 

The short, paved walk from the better-known Congwong Beach takes you to a secluded stretch of sand in the La Perouse section of Kamay Botany Bay National Park, a 30-minute drive south of the city centre. The calm water at this little beach makes it great for a snorkel or paddling with kids. Surrounded by lush vegetation, the cove feels miles away from the city, although there’s also easy access from a nearby road if you don’t want to walk from Congwong Beach, and there is plenty of parking nearby. Bring a beach umbrella, though, as there is limited shade. Little Congwong was previously an unofficial clothing-optional beach, although this is now discouraged.

Burning Palms Beach, Royal National Park   

There are some great little beaches in the Royal National Park, an hour’s drive south of Sydney. Garie and Wattamolla beaches are the most accessible, but there are plenty of others to seek out, including Burning Palms Beach. Park at Garie Beach and walk south along the Coast Track, past North and South Era beaches, or brave the steep 20-minute walk from Garawarra Farm car park. The northern end of the beach’s headland is dotted with historic beach shacks, built by miners from nearby Helensburgh in the 1930s. Note that the surf can be strong and the beach is not always patrolled. 

Store Beach, Manly

There’s a beach on the harbour side of Manly‘s protected North Head that’s so secluded it’s only accessible by water. Store Beach was originally the site where ships would unload provisions for Sydney’s old Quarantine Station, which was used to isolate arriving passengers suspected of carrying infectious diseases. Now part of Sydney Harbour National Park, the quarantine buildings have been transformed into the Q Station boutique accommodation.  

You can reach Store Beach via a challenging rock hop at low tide from nearby Collins Flat Beach, but most people make their way here by boat. Hire a kayak from Manly Kayak Centre and paddle your way there in about 20 minutes. Keep an eye out for little penguins, which use the reserve as a breeding ground. 

Turimetta Beach, Narrabeen Head  

Turimetta Beach, a 30-minute drive from Manly on Sydney’s Northern Beaches, is so secret it disappears at high tide. Low tide exposes a small stretch of sand, interesting rock formations and carvings. It’s bordered by Turimetta Head to the north and Narrabeen Head to the south, with access from the Bicentennial Coastal Walk or via the rock platform from Narrabeen Beach. Backed by steep cliffs, the beach is popular with surfers. It’s not patrolled and the surf is strong, but the south end’s large, flat rocks and rock pools are great for kids to explore.
