This botanical paradise, 50km north of Cervantes, contains a staggering 820 plant species, many of them rare and endemic, such as the pine banksia (Banksia tricupsis) and Mt Lesueur grevillea (Grevillea batrachioides). Late winter sees the heath erupt into a mass of colour, and the park is also home to the endangered Carnaby's cockatoo. An 18km circuit drive is dotted with lookouts and picnic areas. Flat-topped Mt Lesueur (4km return walk) has panoramic coastal views.
