The car park for this walk is at the intersection of Norman Wade Scenic Drive and Cape Nelson Lighthouse Road (38°25′06.79″S, 141°32′30.68″E) (Google Maps). You'll have to ignore Google Earth's interpretation. In fact, the walk is a loop course that begins and ends at this car park.
Be sure to pick up a brochure at the car park before you start, because the trail has numbered pegs which refer to the numbers in the guide. You can expect to see echidnas, lizards, lots of birds, banksias, wattle, moonah, and more.
