It covers the low granite hills to the north of the town of Walpole and is covered largely by forests of karri (Eucalyptus diversicolor) and red tingle (Eucalyptus jacksonii), two of the world's largest trees. The three tingle species are unique to the area between the park and the coast and the only eucalypts to be buttressed, a feature which reflects the moist conditions prevailing within the park. On exposed areas where continuous rain washes away soil, a low heathland is the dominant vegetation.
Annual rainfall at Walpole is around 1,200 mm (47 in). 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.
