When it comes to winter family getaways, Sydney is often overlooked in favour of snowier spots further south. But the Harbour City is full of unexpected wintry delights—both indoors and out. Think cosy corners, hearty pub fare, awe-inspiring exhibitions, and close-up wildlife encounters. Add kids into the mix, and it becomes even more magical.

From spotting humpbacks along the Bondi to Coogee Coastal Walk and soaking up Harbour views aboard the iconic Manly Ferry to sampling global eats at Hay St Market, we've rounded up some of the best family-friendly activities to help you plan your next escape. Plus, if you're keen to stay in the city, Marriott Bonvoy is offering 10% off your stay across six hotels—all you need to do is sign up (for free). It's also the perfect excuse to extend your stay.

Pack your puffer and rally the little ones—here are nine top family-friendly things to do in Sydney this winter.

If the weather turns grizzly or you're facing decision paralysis over what to eat, Hay St Market—Sydney's newest hawker-style foodie hub—is an ideal spot for the whole family to explore. Bringing together 48 traders and over 25 international cuisines under one roof, the market buzzes with lively, aromatic stalls serving everything from freshly-baked sourdough and creamy cannoli to juicy citrus, melt-in-your-mouth sashimi, and premium cuts of meat. To keep the food adventure going, walk across to Spice Alley in Chippendale—just a short stroll from Four Points By Sheraton Sydney, Central Park.

While many botanical gardens around Australia boast magnificent, manicured grounds, few compare to Sydney's historic Royal Botanic Garden. Home to more than 27,000 plant species and boasting uninterrupted views of Sydney Opera House and Sydney Harbour Bridge, it's the ultimate spot to roll out a picnic rug and absorb some precious winter rays.

There are plenty of things to keep the little ones entertained, too. Wander through the aromatic herb garden, the vibrant wildflower meadow, and the sun-drenched succulent garden—or book the kids into a nature-inspired craft workshop.

Revered as one of the most picturesque walks along Australia's east coast, the Bondi to Coogee Coastal Walk is a year-round favourite—but it's especially popular from May to November during the annual humpback whale migration. The walk stretches about six kilometres one way, is suitable for all fitness levels, and offers vantage points aplenty, including Ben Buckler Point, Clovelly Beach, Waverley Cemetery, and Gordon's Bay. Mornings and late afternoons are the best times to spot whales, which often breach close to shore—but bring a pair of binoculars to get an even closer view of the action.

Keen to check out one of Sydney's iconic beaches? Jump aboard Sydney's historic Manly Ferry. Departing regularly from Circular Quay, the 30-minute journey is packed with spectacular Sydney Harbour views, including the Sydney Harbour Bridge, the Sydney Opera House, and Kirribilli House.

A must on any first-timer's Sydney itinerary, Manly offers plenty to explore once you arrive, with viral eateries like Norma's Deli, Butter Boy, and Chica Bonita regularly drawing crowds daily. Plus, the ferry terminal is just a quick stroll from Sydney Harbour Marriott, Circular Quay making it the perfect day-trip if you're staying close by (and scoring 10% off your stay).

Speaking of ferries, hop aboard the Milson's Point Wharf ferry at Circular Quay and spend a day exploring Luna Park—one of Sydney's most iconic amusement destinations. The heritage-listed theme park blends vintage carnival charm with modern thrills like the sky-high Coney Island Devil's Drop, the gravity-defying Rotor, the classic Ferris Wheel, and The Big Dipper—the world's first-ever double-launch single-rail rollercoaster.

Taronga Zoo is a playground for all ages that rolls education and fun into one, and has offered unforgettable wildlife encounters for over 100 years. Committed to wildlife conservation, the zoo is home to 4,000 animals across 350 species, including majestic African lions and Western Lowland gorillas, playful fairy penguins, and adorable pygmy hippopotamuses. To kick the adrenaline up a notch and see some wildlife from a new perspective, strap in for a climb on the zoo's thrilling high ropes course.

Home to over 4,000 animals across more than 300 species, SEA LIFE Sydney Aquarium is a sample of the seven seas right in the heart of the city. With immersive themed zones like Jurassic Seas, Shark Valley and Penguin Expedition, it showcases the world's largest variety of Australian aquatic life—and has become a rite of passage for Sydneysiders and young visitors alike.

Highlights include Pig, the resident rescue dugong, up-close shark scuba encounters, and a walk-through tunnel where rays and sharks glide overhead. Plus, it's just moments away from W Sydney, making it well within reach for an easy yet exciting day out.

Once a convict gaol and shipyard, Cockatoo Island is now a UNESCO World Heritage-listed site just nine minutes by ferry from Barangaroo Wharf. The largest island in Sydney Harbour, it offers a fascinating mix of historical tours suitable for all ages, plus regular cultural exhibitions and events. After exploring, pull up a seat at one of the family-friendly waterfront cafes and watch a flurry of boats glide past—and if you're staying at Pier One Sydney Harbour, take the scenic route back and wander through Barangaroo.

The Art Gallery of NSW is a cultural cornerstone and arguably one of the most significant art galleries in the state — if not the country. While it's known for showcasing a program of both local and internationally acclaimed artists, it also offers a mix of compelling creative activities for the little ones, including Australia's first children's art library on lower level 3, weekly Storytime sessions, and interactive exhibitions. This winter, check out the annual Archibald, Wynne and Sulman Prize (on display until August 17), and the Young Archie finalists.

Down by the Harbour, The Museum of Contemporary Art Australia is the only public museum dedicated exclusively to contemporary art in the country. A must-visit for modern art lovers, it hosts a rotating lineup of globally acclaimed artists—including Cerith Wyn Evans' monumental light sculptures, on display from June until October. Families can also enjoy drop-in drawing classes, and unstructured creative art play for kids under five.
