In spring and summer, the karri canopy bursts into white flowers. The rowdy calls overhead will be from flocks of purple-crowned lorikeets. Birdwatchers may be lucky to spot honeyeaters, wrens, fantails and robins. Sit quietly and keep your eyes peeled on the undergrowth.
This park is also home to Western Australia's most famous climbing karri tree.
The forest is home to many small native animals. These include quenda, quokkas, mardos and dunnarts. It's unlikely you'll see these shy and elusive creatures. But it's good to know they're here.
Take a drive on the Karri Forest Explorer that winds 86 kilometres through some of the south west's most magnificent karri forest.
