10 Secret Gardens You Need To See In Full Bloom

Lose track of time, and yourself, in one of the most magical secret gardens in Australia.

There’s a reason why the children’s novel, The Secret Garden, remains enchanting more than a century beyond its release. To glimpse an unspoiled world, cloaked in flourishing plant life and elusive wildlife that evidently tend to themselves, evokes a timeless curiosity in what lies beneath.

In pursuit of these natural havens during every Aussie adventure, we’ve rounded up our top picks for you to hunt down yourself. From spectacular seasonal blooms to unexpected surprises, the country’s best secret gardens connect you to nature in extraordinary style.

1. Wendy’s Secret Garden, NSW

A totally immersive art gallery, Wendy Whiteley’s Secret Garden on Sydney’s north shore is practically spiritual. One of Australia’s best “hidden" gems, the garden is the scrupulous handwork of Wendy Whiteley, wife of late artist Brett Whiteley, and it flows with every imaginable shade of green.

Dotted through the space, which is set on a steep hill that rolls down to Sydney Harbour, are sculptures and many other endearing artefacts. Once you reach the garden’s centre, you’ll also find chairs and benches to be perched upon as you soak up the wonderment. Bird baths, cherubs, an ancient wheelbarrow and a metal fountain from the late Margaret Olley, another iconic Sydney artist, await amid a manicured mass of palms, shrubs and trees.

The Northern Territory is made for road trips, and this one hits all the highlights.

Craggy mountain ranges, inviting waterholes, ochre soil: the landscape of the Northern Territory is asking to be explored by road and foot. There are many iconic road trips to choose from here, but none so all-encompassing than the roughly 3000 kilometres of sealed road that make up Explorer’s Way.

Spend 14 days (or more, to really make the most of it) driving this route from Adelaide, hitting the NT near the small settlement of Kulgera before later finishing in Darwin. Along the way, you’ll find nearly all the territory’s most iconic sights.

Discover some of the top highlights that make Explorer’s Way one of Australia’s most incredible road trips.

1. Alice Springs

Recently hitting the big screen again with the story of The Kanagroo Sanctuary , there’s a lot to surprise you in Alice Springs.

Three distinct desert habitats – desert rivers, sand country and woodland – are recreated over 1300 hectares at Alice Springs Desert Park . Time your visit for a presentation or a free bird show.

Later, turn your attention to the skies above, taking a dive into local astronomy at Earth Sanctuary . You’ll find a range of experiences, from a 90-minute toe-dip into the stars through to an overnight adventure.

Alice Springs packs a surprising punch with its tasty dining options, including pub grub and unique brews at Alice Springs Brewing Co , tapas and pizza at Epilogue Lounge and tasty cafe fare at the quirky Page 27 .

2. Tjoritja/West MacDonnell National Park

Beginning 15 minutes from Alice Springs and stretching across 161 kilometres, Tjoritja/West MacDonnell National Park is packed with striking ancient landscapes and inviting water holes.

Visit Standley Chasm – traditionally known as Angkerle Atwatye, meaning ‘Gap of Water’ – to take in its bold red and orange hues, and to observe the diverse bird species, lizards and wallabies that call it home.

Cool off in one of several picturesque natural swimming holes, like Ellery Creek Big Hole and Ormiston Gorge.

3. Uluru & Kata Tjuta

Visiting the Cultural Heart of Australia is something everybody should experience. There are so many side trips in the Red Centre you could easily spend a week here, but to get the most out of a short time, park the car then get out on foot.

Take the 10-kilometre Base Walk around the entirety of Uluru or join a free, ranger-guided Mala Walk along part of the base, learning about Tjukurpa (creation stories) and geology as you go.

For a change of pace, wait until nightfall and wander through the iconic Field of Light display by celebrated artist Bruce Munro, or see the Wintjiri Wiru lightshow that shares the ancient Mala story using drones, lasers and projections.

4. Tennant Creek

Tennant Creek was Australia’s third-largest gold mining town in the 1930s, and visitors can discover that history at Battery Hill Mining Centre – and even try their own hand at gold fossicking.

For a completely different side of history, pop into Nyinkka Nyunyu Art & Culture Centre , which preserves and shares Warumungu culture through art, performance, a museum and more.

Just outside town, find the ancient granite boulders of Karlu Karlu (Devils Marbles). A site integral to important stories held by the Warumungu, Kaytetye, Warlpiri and Alyawarra peoples, the boulders appear to almost have dropped out of the sky and seemingly continue to defy gravity.

5. Mataranka

A town made famous by the novel We of the Never Never by Jeannie Gunn (and a movie of the same name), Mataranka is also known for its sandy-bottomed thermal pool, Bitter Springs , within Elsey National Park. Follow a 500-metre loop track around these spring-fed pools that stay a toasty 34°C year-round, before choosing your favourite spot to dive into. Enjoy the local birdlife while you relax.

Elsewhere in the park, find historical sites, several scenic walks and Roper River, which is perfect for boating and fishing.

6. Nitmiluk National Park

Nitmiluk National Park is sandstone country, with 13 stunning gorges and plenty of waterfalls waiting to be explored.

One of the most beautiful spots can be found along the 62-kilometre Jatbula Trail, a five-to-six day bushwalk that follows an ancient Jawoyn songline from Nitmiluk Gorge to Leliyn (Edith Falls). Numbers are restricted and book out quickly, so be sure to plan well ahead. Not up for the hike? Drive right up to the falls and enjoy a dip without the challenge.

Elsewhere, explore Nitmiluk (Katherine) Gorge. Paddle a kayak through the river running through the canyon, or save your energy on a Nabilil Dreaming Sunset Dinner Cruise , discovering the stories and ways of the Jawoyn people while enjoying a candlelit dinner as the cliffs around you shift colour and glow with the changing daylight.

Continue your cultural journey at local art centres like Godinymayin Yijard Rivers Art & Culture Centre or Mimi Aboriginal Art & Craft .

7. Litchfield National Park

Just over an hour’s drive from Darwin lies the beautiful Litchfield National Park. It’s famous for stunning waterfalls and swimming holes, including Buley Rockhole, Wangi Falls, Florence Falls and Tjaynera Falls.

Here you’ll also find hundreds of giant – and magnetic – cathedral termite mounds that are truly a sight to see. Ageing up to 100 years old, you won’t find mounds like these outside the northern parts of Australia. Stroll along the accessible boardwalk to see them up close.

8. Darwin

This list wouldn’t be complete without the territory’s capital city: Darwin. Situate yourself upon arrival with a stroll through the main streets, admiring the many art murals by local, interstate and international artists. They’re all remnants of the annual Darwin Street Art Festival , one of Australia’s longest running street art festivals.

Stop to recharge along Darwin’s Waterfront Precinct , an area of delectable restaurants, public swimming pools and free events. And, of course, it would be wrong to leave the city without enjoying a bowl of laksa at Mindil Beach Sunset Market as the sun goes down.
