20 hidden natural wonders you’ve probably never heard of

The hidden natural wonders that are wowing visitors, without the crowds.

Australia is home to some of the most iconic natural landmarks on Earth – think Uluṟu, the Great Barrier Reef and Wineglass Bay. But a new study has uncovered 20 jaw-dropping Aussie destinations that deserve just as much attention – and yet most people have never heard of them.

The research by Mitsubishi Motors Australia analysed over 50,000 Australian locations using data from TripAdvisor, Google and SEO platforms. The goal? To uncover places with exceptional visitor ratings but minimal online searches – aka, Australia’s best-kept secrets. From sacred sites in the Northern Territory to lava tubes in Queensland, these are the hidden spots that offer big wow factor without big crowds.

1. Gunlom Falls, NT

This legendary Top End icon has finally reopened after a six-year closure – and it’s as jaw-dropping as ever. Located within World Heritage–listed Kakadu National Park, the steep but rewarding climb to natural infinity pool Gunlom Falls reveals panoramic views over the escarpment, while the lower pool is equally magical. It’s a sacred site to the Mirarr Traditional Owners, so visitors are asked to tread respectfully and follow all signage.

2. Mount Coot-tha Summit Lookout, Qld

A Brisbane local favourite that deserves wider acclaim, the Mount Coot-tha Summit Lookout serves up sweeping vistas over the city skyline to Moreton Bay. Just 15 minutes from the CBD, it’s the perfect place to watch the sunrise or soak in golden hour with a coffee from the summit cafe. The surrounding forest trails and Botanic Gardens make it one of Queensland’s most accessible escapes.

3. 75 Mile Beach, K’gari, Qld

A beach that doubles as a national highway and a landing strip? That’s 75 Mile Beach on K’gari, the world’s largest sand island. Stretching along the island’s eastern coast, technicolour sand cliffs, crystal-clear creeks like Eli Creek, and natural rock pools such as the Champagne Pools flank this wild and windswept stretch of sand. Four-wheel-drive adventurers will relish the freedom of the open sand, but it’s the untouched beauty that leaves the biggest impression.

4. St Columba Falls, Tas

Hidden deep in Tasmania’s north-east near the town of Pyengana, St Columba Falls is one of the state’s tallest permanent waterfalls, plunging more than 90 metres through a forest of tree ferns, sassafras and myrtle. The short rainforest walk to the falls is atmospheric, and it’s not uncommon to spot platypuses in the river below. Few make the detour, but those who do are richly rewarded.

5. Grassy Hill Lookout, Qld

Cooktown’s most panoramic vantage point, Grassy Hill, is steeped in both natural beauty and complex history. In 1770, it was from this hill that Captain Cook climbed to chart a safe passage for the Endeavour after damaging the ship on the Great Barrier Reef. Today, the lookout offers panoramic views over the Coral Sea and Endeavour River, and serves as a reminder of the need to reflect on both the natural and cultural significance of place. The sunsets are particularly memorable, painting the landscape in warm hues of gold and orange.

How many have you ticked off?

Mythical, historical and most of all, spectacularly beautiful, Buchan Caves demands you take your time – and a tour.

In the pools of water, so still they could be mirrors, the reflections of the stalactites make these limestone towers seem even taller. Almost 400 million years ago, an underground river carved through the rock to create the Buchan Caves . Now, artworks created by dripping water adorn these subterranean galleries: stalactites hanging from the ceiling, pillars connecting some to the ground, even curtain-like wave formations clinging to the stone.

“This is called the Fairy Cave because it’s full of fairy dust,” a guide tells visitors as they enter a cavern glittering with “calcite that’s solidified into thousands of tiny little diamond shapes”. Buchan Caves is Victoria’s largest cave system, but Fairy Cave is a highlight and, along with nearby Royal Cave, is accessible only by tour. Naturally cold, naturally dark, these caverns deep below the surface light up as the local experts tell their stories.

Among the hundreds of caves, some can be easily accessed from the surface. For instance, a casual stroll along the FJ Wilson Interpreted Walk, as kangaroos watch on from beneath acacia trees, leads into the 400-metre-long Federal Cave and its natural steps of white limestone. A slightly longer track, the Granite Pools Walk heads through soaring forest down into moss-covered gullies where the calls of lyrebirds trill through the leaves.

A quick history lesson on Buchan Caves

Among the geology and the nature are millennia of history. This part of East Gippsland connects the high country to the coast and was long a place of refuge for the local Gunaikurnai people on seasonal migrations to the mountains. Archaeological studies show humans lived here up to 18,000 years ago, with artefacts such as small stone tools found around the site. But not too far into the caverns – oh no! The Gunaikurnai didn’t dare venture deep into the dark at Buchan Caves, telling stories they were inhabited by gnome-like nyols (small grey-skinned creatures that could steal memories).

By the early 1900s, more people had started to hear about these incredible caves and so the Moon family set up home at the site and started to run tours below ground for intrepid visitors. More than a century later, their historic residence is available as accommodation, with the three-bedroom house sleeping up to eight people and now equipped with modern amenities the Moons could only have dreamt of.

But whether you stay overnight or just spend the day here, it’s worth taking your time to explore more than just the main caves, to get a deeper understanding of one of Victoria’s fascinating geological attractions.
