You won't be very far into this challenging 7km walk - just 500 metres or so - before you'll come across the opening of Cooleman Cave. Make sure you've got a torch with you so that you can explore inside. Back out in the sunshine, follow the often dry Cave Creek. Don't move too quickly across the surface because you can find ancient fossilised shells of brachipods and sea lilies on its bed.
There are some unique longer views of the limestone gorge and on to the snow grass plains surrounded by the wooded slopes of Gurrangorambla Range and Tom O'Rourkes Peak. For photographers, it's an absolute gem of an amble. Birdwatchers, too, will be well-rewarded with sightings of magpies, flame robins, and soaring wedge-tail eagles.
Please ensure sure you're properly kitted out for this walk. You'll need good boots, because the surface is often uneven and wet, torches and jackets for the caves, and a topographic map.
It's a good idea to fill in the free trip intention form and hire a PLB before you set out. Bring a topographic map and compass or GPS.
