Along the steep granite hills fringing the Walpole-Nornalup channel, the south-western shore of the Nornalup Inlet, and along the Deep and Frankland rivers, stands of karri (Eucalyptus diversicolor), marri (Corymbia calophylla), red tingle (E. jacksonii) and yellow tingle (E. guilfoylei) dominate the tree line. These areas are known locally as The Knolls and they are exceptionally scenic.
The narrow channel connecting the two inlets is about 200m wide, a kilometre long and about two metres deep. You can fish in the channel although it has a rocky bottom.
