Bungonia sits at the point where the Southern Tablelands stop being gentle. About 30 kilometres southeast of Goulburn, the limestone plateau suddenly cracks open into a gorge system that drops over 300 metres to the Shoalhaven River below. The Bungonia Gorge is the deepest river canyon in Australia accessible by foot, and the surrounding state conservation area protects one of the richest cave networks in New South Wales. For visitors expecting another pastoral town on the highway, Bungonia tends to surprise.
The gorge and what makes it unusual
Bungonia Gorge cuts through Silurian-era limestone laid down roughly 430 million years ago. The result is a landscape that behaves differently from almost anywhere else on the Tablelands: sheer white cliffs, sudden drops, narrow slots, and a river that disappears and resurfaces through cave passages. The Shoalhaven River runs through the base of the gorge, cold and clear, with swimming holes that reward the steep walk down.
The area is managed as the Bungonia National Park, part of a larger conservation area that extends across the plateau and gorge rim. Entry requires a vehicle day-use fee, collected at the park entrance. The park is open year-round, though conditions in the gorge can be hazardous after heavy rain.
Walking tracks: four grades, one serious commitment
NSW National Parks maintains four marked walking circuits inside Bungonia, ranging from an easy 1-kilometre rim walk to the full Red Track, a 9-kilometre loop that descends to the river and climbs back out. The Red Track takes most walkers between four and six hours and includes fixed ropes on the steepest sections. It's graded as hard for a reason: the descent is knee-testing and the return climb leaves nothing in the tank.
The Blue Track offers a middle option, dropping partway into the gorge and returning via the plateau rim. It's quieter than the Red Track on most weekends and gives a good sense of the cliff faces without committing to the river. Shorter tracks along the rim work well for families or anyone who wants the views without the descent.
- White Track: 1 km, easy rim walk, suitable for all ages
- Blue Track: 5 km, moderate, partial gorge descent
- Green Track: 6 km, hard, includes rope sections
- Red Track: 9 km, hard, full descent to the Shoalhaven River
Caving at Bungonia
Bungonia holds more than 200 mapped caves, including Bungonia Cave itself, one of the longest in NSW. Most caves are closed to unguided visitors to protect resident bat colonies and delicate speleothem formations. A small number of wild caves can be explored by groups with the right equipment, permits, and a caving club affiliation. The Speleological Society of Australia publishes guidance on gaining access and on responsible caving practices in the area.
The plateau above the gorge also contains several open cave entrances that are visible from walking tracks. They make for good photographs but should not be entered without proper equipment. The drops are serious.
Camping and practical details
The park operates a bush campground near the park entrance, with pit toilets, picnic tables, and fireplace facilities. There's no powered water supply at the campground, so visitors need to bring their own drinking water. The campground suits tent campers and small campervans. Book through the NSW National Parks site, particularly for long weekends, when the gorge draws climbers and cavers from Sydney and Canberra.
The nearest town with fuel, supplies, and accommodation is Marulan, about 20 minutes to the south on the Hume Highway. Marulan is a compact Southern Tablelands town worth a stop in its own right, with a bakery and roadhouse serving travellers heading to the coast.
Goulburn is the closest regional centre, offering full services including supermarkets, motels, and a hospital. The drive from Goulburn to the Bungonia park entrance takes around 35 minutes on sealed road. Goulburn also sits within easy reach of other dramatic Tablelands landscapes, and anyone spending a few days in the area should consider the range of Braidwood day trips to the southeast, where the Tablelands drop toward the coast through equally striking escarpment country.
Rock climbing
Bungonia is one of the top sport climbing destinations in southern NSW. The gorge walls offer limestone sport routes ranging from grade 14 to grade 32, with the bulk of established lines sitting in the 18 to 25 range. The main climbing sectors sit above the gorge floor and are reached via the walking tracks. Anchors are in place on established routes; new bolting requires a permit from the park.
Climbers camp at the main campground and walk in each morning. The exposed limestone dries quickly after rain, which is one reason the area draws climbers even in shoulder seasons when other crags stay wet.
When to visit
Autumn and spring suit the gorge walks best. Summer can be genuinely hot on the plateau and brutally exposed on the descent, while winter mornings on the rim see frost. The gorge floor stays cooler than the plateau in summer, which makes the Red Track more manageable as an early-morning start. After significant rainfall, the gorge tracks flood and Parks NSW closes access; check conditions before driving out.
Bungonia rarely crowds the way that Blue Mountains destinations do, even on school holidays. It's the kind of place where you'll share the rim with a few other walkers and probably have the river pools to yourself by mid-morning on a weekday.
