Mount Frankland (411 metres), known as Caldyanup to the aboriginal inhabitants, is a granite peak which offers panoramic views across the landscape.

The mountain was named in 1829 by Thomas Braidwood Wilson after George Frankland, who was then Surveyor General of Tasmania.

On the 422-metre high peak of Mount Frankland, though no rain gauge has ever been installed, annual rainfall is probably around 1,500 mm (59 in).

Most rain falls between May and August, but unlike drier parts of southwestern Australia, showers are not infrequent even during the summer.

There are picnic areas with gas barbecues and toilets 100 metres from the car park, and a treetop-level wilderness lookout further on.
