14 gorgeous natural wonders just a day trip from Sydney

This trio of rocky wonders easily ranks among the nation’s most famous natural landmarks, alongside the likes of Uluru and the Great Barrier Reef. Each year, millions of people flock to the Blue Mountains, 100 kilometres west of central Sydney, to see this distinctive rock formation. A Dreamtime story tells of Meehni, Wimlah and Gunnedoo, three sisters from the Katoomba people, who were turned to stone to protect them from a great battle. The most dramatic views of the Three Sisters can be found at Echo Point Lookout, where there’s also an excellent visitor centre with information about the area and local First Nations history. For a closer look, follow the trail till you reach Honeymoon Bridge, which connects with the first sister. If you’re in an athletic mood, there are plenty of walking trails to explore in the area too, such as the Prince Henry Cliff walk or the Dardanelles Pass loop walking track.

Time Out tip: To upgrade your experience, you can’t beat the Scenic Skyway. This glass-bottomed cable car soars over 270 metres above the rainforest canopy, for 720 metres between clifftops. You’ll also get eyes on Katoomba Falls and the Jamison Valley stretching out to the horizon.

Look, don't expect the icy blue shade of the Turkish Pamukkale thermal baths at this 'blue pool'. What we can promise you is when the sun strikes this bushland pond at just the right angle, you’ll see the waters of this natural swimming spot turn an otherworldly shade of aquamarine blue. Part of the waterways that make up the Carrington Falls, the Blue Pool is not the only reason to visit. Budderoo is one of NSW’s most beautiful natural retreats, and there are plenty of other spots for a dip if swimming holes are your love language, including the gorgeous Nellies Glen and its picture-perfect falls.

Time Out tip: The terrain of this area is gorgeous, but it's not the easiest to explore, especially if you have children in tow or mobility issues. The good news is that instead of parking up top at the larger Nellies Glen car park, there's another smaller carpark off Jamberoo Mountain Road just 100 metres from your destination.

Once upon a time, old mining locomotives used to pass through this 400-metre long tunnel. Now if you stand in the man-made chiselled passage and stare upwards, you'll think you're gazing at starry skies. But that’s not the cosmos overhead; it's huge colonies of fungus gnat larvae – better known as glowworms. This fantastical cave in Wollemi National Park just north of the Blue Mountains produces a light show thanks to thousands of tiny, bioluminescent critters who call this cavernous place home. Think of it as Mother Nature’s version of Vivid, without the crowds. 

Time Out tip: It's very dark in the tunnel, so bring a torch or head torch (it must have red light). Whatever you do, don't shine it up at the bioluminescent gloworms since the light distresses the worms and, consequently, your 'starry sky' will disappear. 

A couple of hours' drive from central Sydney, just beyond the Northern Beaches and Barrenjoey Head, the rocky wilds of the southern Central Coast boasts some of the most dramatic landscapes you can find – and it's just 100 kilometres from the city. Most strikingly, the sedimentary rock that makes up this area of coastline has been eroded into beautiful patterns, as different strata of the stone, known as Liesegang rings, have been revealed. The best examples can be found on the eight-kilometre Bouddi Coastal Walk, which runs between the eastern end of Putty Beach to MacMasters Beach. It’s a hike best suited to more experienced walkers, but the stunning scenery of this coastal heathland is well worth the slog.

Time Out tip: If you find yourself at MacMasters during May to November, it's whale watching season. Once you’ve enjoyed a feast for the eyes, treat yourself to a gastronomic feast at The Fat Goose in Killcare.

By pure fluke, many thousands of years ago, an Instagram icon was born when two sinkholes in coastal rocks serendipitously created a pair of nearly perfectly cylindrical pools in the shape of – you guessed it – the number eight. In recent years, visitors have flocked to the Royal National Park in droves, hoping to ‘gram it up while splashing about in this nautical numeral. Contrary to the plural implications of its name, there is just a single figure eight pool here, although there are several other rock pools to plunge into nearby. However, be warned: a visit should only be attempted at low tide when the waters are calm, as injuries have occurred when rough seas have lashed this corner of the NSW coast.

Time Out tip: Photogenic as these pools may be, their popularity has led to them being maddeningly overcrowded. Head there in the early morning or on weekdays to beat the tourist crush. Also be sure to use the loo and carry drinking water before your adventure: it takes more than an hour to walk to the pools from the nearest parking lot.

Less than a two hours' drive south of Sydney, this gorgeous gusher is very impressive. In fact, with jets of salty spray reaching heights of 25 metres or more, it’s the largest ocean blowhole in the world. This natural spectacle occurs when waves surge through an underwater channel in the rock, driving some 50 litres of water high into the air. How's that for a splash zone? This isn’t so much a PSA as it is a rite of passage when visiting Kiama: you will get wet. Embrace the seaside sogginess for the most dramatic, up-close views of this rare phenomenon – but don't take unnecessary risks. 

Time Out tip: The main strip in Kiama has adorable cafés and plenty of boutiques for window shopping. Also, the cute-as-a-button town of Berry is just 20 minutes by car from Kiama.

Along the Hawkesbury River is Dangar Island, just 1.5 hours from Sydney. Getting there is part of the charm: catch a train from Central to Hawkesbury River Station, stroll a few minutes to the wharf, then hop on a short ferry ride across the water. Once you arrive, you’ll notice something missing (in a good way) – cars. You'll need to explore this car-free island on foot or by bike. With walking tracks through the bush, quiet beaches and no traffic noise, Dangar Island is the ultimate digital detox. It’s the kind of place where you can switch off your phone, slow your pace and enjoy the peace and quiet.

Time Out tip: The name Dangar is not 'danger' misspelled. It's named after Henry Carey Dangar, who bought the island in 1864. Prior to this, it was called Mullet Island, named by Governor Phillip in tribute to the ample fish stocks in the region.

It’s not exactly clear whose nuptials were ruined by a sagging, square, chalky-looking wedding cake, but whoever they were, they christened this enduringly popular wedge of sandstone with the catchy epithet that's stuck ever since. In recent years, it has become an Insta-magnet for snap-happy visitors ready to strike a pose on this pearly platform. Unfortunately, because of the rock’s precarious location, it is expected to collapse into the sea at some point in the not-so-distant future, so fencing now prevents visitors clambering all over it. Please, stay behind the fence; it’s for your own good.

Time Out tip: There are so many beauties to behold in the Royal National Park. We suggest you put that phone down and enjoy your visit IRL. And if you trek on down 20 minutes' down the coastal path, you’ll find the picture of serenity at Marley Beach – the perfect place to escape your screen.

Who knew you could find the oldest open cave system in the world in a little old NSW town? It took more than 340 million years for geological processes to carve these cathedral-esque caverns from the soft limestone of the Blue Mountains. Fortunately, it’ll take you a lot less time to make the 175-kilometre drive from Sydney to see them for yourself. 

Time Out tip: If the subterranean splendour of the caves is really feeding your nature fix, go to Kanangra-Boyd National Park that's just a ten-minute drive away. Visit the look-out point with views of the Kanangra Walls and Mount Cloudmaker.

When it comes to expanses of water, Sydneysiders are spoilt for choice. Sheltered from the Pacific Ocean by the insular peninsula of the Northern Beaches, Pittwater is a thriving waterway fringed by the lush greenery of the Ku-ring-gai Chase National Park. The incredible natural beauty and rich Indigenous history is less than 45 kilometres from Sydney CBD. And there are so many ways to enjoy and explore this area: paddleboarding, fishing, coastal hikes, bushwalks, swimming, sailing, cycling and jogging. 

Time Out tip: Our favourite way to experience Pittwater is by kayak. The sheltered waters here are gentle and the meditative calm you feel while gently floating upon them is the perfect way to shed the stress of the city.

Gorge by name, gorge by nature, this breathtaking canyon on the eastern edge of the Blue Mountains National Park makes for a surprisingly versatile day trip. You can head to Tunnel View Lookout or Mount Portal Lookout for some panoramic views, or get up close and personal on the Glenbrook Gorge track. For something a little more relaxed, take the easier trail to Jellybean Pool, where you can take a dip if you’re in the mood (although not immediately after rain). While you’re down here, surrounded by imposing boulders and beautiful bushland, it’s easy to imagine you’re miles from civilisation, when in fact, you’re just an hour away from the city. 

Time Out tip: Glenbrook is just an hour on the train from Sydney Central, so top up that Opal card. From the town centre, it’s a 20 minute walk to the Jellybean Walking track and another 10 minutes to Tunnel View Lookout, so you can enjoy a day in nature, without having to jump behind the wheel. 

In the heart of the Blue Mountains, along the National Pass walking trail, you’ll find Princes Lookout and the oh-so-beautiful  Wentworth Falls. Once here, you've got two choices: take a look at the Falls which can be done and dusted in 15 minutes flat, or, for a more hardcore adventure, take a three-hour hike through the eucalypt forest to see the other falls in the area – Empress, Silvia and Lodore Falls. The mountain track hugs the cliffs, overlooking the Jamison Valley, and it ends with the glute-destroying Giant Stairway – at least you'll have buns of steel.

Time Out tip: The looped track is just over five kilometres, however, it’s a hard trek so we reccommend you pack a bag with water, sunscreen and snacks for the journey. Once you've finished your adventure, a more substantial feed can be had in nearby Katoomba. For the real gastronomes, Darley’s Restaurant at Lilianfels Resort and Spa is pure heaven. 

To the untrained eye, these caves are pretty spectacular, but to a geology nerd, they’re downright mind-blowing. Stalactites, stalagmites, flowstones, cave coral, helictites, stone shawls and subterranean lakes – it’s geological bingo down here, including some incredibly rare rock formations that are seldom seen by the general public. Don’t miss the accessible walking track to Victoria Arch, one of Wombeyan’s most epic cave chambers. It's just over a three-hour drive from Sydney, so it is doable as a day trip but you can also camp in the area or rent a cosy cabin to make a weekend of it. There are powered sites, parking access, a visitors' centre and a kiosk.

Time Out tip: The four main caves can be explored via guided tours, or with a choose-your-own-adventure approach – with the new viewing platform near Fig Tree Cave making the amazing sites now accessible for people with limited mobility. 

Australia is the land of big things: the Big Banana, the Big Prawn, the Big Ned Kelly – the list goes on. But of all the big things in this big land of ours, few can compete with the truly epic dunes of the Worimi Conservation Lands at Anna Bay in Port Stephens. These shifting sands, just north of Newcastle, stretch for 32 kilometres, over a footprint of more than 4,200 hectares. At just over 2.5 hours' drive from Sydney, this is the furthest landmark on our list, but as one of the Southern Hemisphere’s most impressive vistas, the road trip up the Central Coast is well worth it. There’s camel riding, 4WD, quad biking and sand-boarding all year round. If you’re a photographer, the dawn light over the dunes is renowned for its photo-ready majesty.

Time Out tip: If you've got the energy, drive a little further up to Shoal Bay. This coastal town is the starting point of the breathtaking Tomaree Coastal Walk. If you start here, the 27 kilometre walk actually brings you all the way round to the sand dunes so you're rewarded for all your hard work.
