1890s first European to see the cave is Mr Walls who owned the land on which the cave is located.


Greeves Creek is a gorge in the sandstone of the Black Hills. It is located south of Blackheath and has quite impressive narrow passages, with rounded erosional forms in colourful sandstone. The short trail ens at a part of the gorge which is called Walls Cave, but actually it is a shelter formed by the overhanging gorge wall. The cave has some aboriginal paintings and is quite impressive. The site is of special significance to local aboriginal peoples, please show respect and stay within the fenced area. Some passages are water filled and have been equipped with elevated trails more tha a century ago. At the moment there are plans to recreate such a trail through a waterfilled section of the gorge. It is called Underground River, though it is neither a river nor underground.

The walk is not restricted but even as it is a short walk you should always be equipped. Bring enough water, food, good walking shoes, sun protection, and of course a camera. The trail starts at Evan’s Lookout Road, turn off at Walls Creek road and park at the end. It's about a 30 minutes walk to Walls Cave and a little more back uphill. With enough time to see the creek and the cave you should probably plan two hours. While the weather in Australia is mostly dry and warm, you should be careful with bad weather and bushfires. The trail is sometimes closed due to flooding.

There is a second trail called Grand Canyon Loop, which is also quite impressive, but longer.
