The Big Hole walking track
Deua National Park
Fire affected area
Some areas of this park were affected by fire in 2019/2020. You’ll notice some changes to the landscape, as well as signs of recovery. Some areas may remain closed for longer to allow habitat to recover or because we’re repairing park infrastructure. Stay safe with these after-fire tips for visitors.
It’s an adventurous walk from Berlang campground to the viewing platform at The Big Hole as long as you don’t mind getting your feet wet crossing Shoalhaven River along the way.

In 1862, a young man called Boxall used four long saplings, a rope and a candle to explore a deep chasm out in the bushland of southeast NSW. The rubbly bottom he eventually landed on was 96m from the surface. Onlookers were all shaking their heads at his reckless behaviour but also itching to know what he’d found down there inside what is now known as The Big Hole.
Thought to be around 400 million years in the making, this is an extraordinary limestone marvel; a roofless cave which is over 100m deep and 50m wide. It can be reached by walking from Berlang campground, wading across Shoalhaven River, then continuing through dry eucalypt forest and unique nana heath, with expansive views of the park on your journey. The vast open chasm can be viewed from the lookout and, if you’re there in the early morning or late afternoon, you may see its resident lyrebird come out from its ferny grotto to feed. For a more challenging hike, carry on to Marble Arch or return to Shoalhaven River for a picnic and a swim.
