If you are looking for a monster rock, Kokerbin is the spot to check out. At 122m high, it’s thought to be the third largest inselberg in Australia (behind Uluru and Mt Augustus) and contains interesting formations, caves and a deep well. It also provides essential habitat for some very special animals.


Kokerbin Nature Reserve covers nine hectares of remnant bushland and features the 122 metre high Kokerbin Rock.
At the base of the rock visitors will notice Wave Wall, a small-scale version of the famous Wave Rock. The wave feature, likes the famous Wave Rock, was caused by weathering and erosion over many millions of years, worn smooth by the elements.
Next on the trail are the Devil’s Marbles, an interesting stack of balancing granite boulders.
Like the wave formation, weathering formed the ‘marbles’. Weathering that creates smooth rocks such as these is spheroidial weathering and is predominantly created through chemical erosion by rainwater.
The final feature before the rock climb begins is a pioneer well dating from the 1920s. Water was a precious resource in the dry climate and the well would have been vital for early pioneers.
Venturing up the rock is an adventure and chance to explore the formations. The top of the rock offers sweeping views over the landscape.
There are over 500 plant and animal species in the Kokerbin Nature Reserve. A 2009 survey estimated that 21 native mammal, 151 bird, 74 reptile and 10 frog species may occur in the Kokerbin Nature Reserve. This includes several species of conservation significance and some which are only found on granite outcrops in the region.
You may be lucky enough to spot a furry Black-footed Rock Wallaby (Petrogale lateralis) or even a dragon! The Ornate Dragon (Ctenophorus ornatus) darts between rocks and has a distinctive flattened body specialised for a life living under rocks.
Other fauna to keep a look out for include the Chuditch (Dasyurus geoffroii), Brushtail Possum (Trichosurus vulpecular) and Tammar Wallaby (Macropus eugenii).
