One of seven national parks that make up the Walpole Wilderness, Mount Frankland South National Park has large areas of old growth karri and jarrah forest.
A great place to see the huge old karri trees up close is at Swarbrick, once a focal point for people campaigning to protect the forests. Swarbrick also features forest art sculptures that are designed to challenge your perceptions of wilderness.
Experience the jarrah forest and its plethora of understorey species while on a short bushwalk at Mount Burnett. Spring is a great time to visit as the wildflowers put on a colourful show.
The Deep River winds its way through the park on its way to the Walpole Inlet and the Southern Ocean. Cascading over granite boulders at Fernhook Falls, it is one of the few rivers in the South West with an almost completely forested catchment. As a result, although heavily loaded with tannins, the water is of high quality.
The Deep River is officially classed as a ‘wild river’.
Wild rivers are defined as:
…those rivers which are undisturbed by the impacts of modern technological society. They
remain undammed, and exist in catchments where biological and hydrological processes
continue without significant disturbance. (Water and Rivers Commission, 1999).
Parts of Mount Frankland South National Park are accessible via a sealed road from Walpole and the South West Highway. Access to Fernhook Falls is via an unsealed gravel road.
