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.
