Candy Block is a little known outlier of Dryandra Woodland on the Narrogin-Wandering Road near the turnoff to Cuballing. It is a great place to visit in the growing season to see some great flowers and interesting scenery. The whole area is underlain by really ancient (2.8 billion years!) granitic rocks that determine the pattern of ridges, waterways and present day soils. Compare this with much of the northern hemisphere that has lots of sedimentary rocks and was scoured by glaciers only 10,000 years ago.
Candy Block has more dramatic slopes and breakaways and gullies and more variable soils than the main block, that reflect variations in the underlying rock. In particular more resistant laterites on NW-SE dolerite dykes have remained while surrounding soils eroded to form dramatic mesas with steep gullies that makes for a great walking trail.
The Three Mesa Trail below is a 3.5km moderate difficulty walk over 3 lateritic mesas interspersed by dense sheoak, wandoo and powderbark woodland. Good views and wildflowers with different plants on each mesa and the tallest grass tree that I have seen.
The slideshow below gives a snapshot of this remarkable reserve.

Spring orchids are less common. Cowslip orchids are widespread, greenhood, jug, snail greenhood, donkey, blue china and fringed mantis orchids occur in places in sheoak woodland.
Sections of Candy Block are baited monthly to control foxes and feral cats. If you discover a “sausage” style bait on the ground please do not touch, remove or disturb it. Pets are not permitted and all pets are likely to be highly susceptible if taking a bait.
