Willi Willi National Park is accessible by car from Wauchope west of Port Macquarie. The roads through the state forest and the National Park are mainly dirt and gravel but were well graded when we drove through. Park at the Wilson River Picnic Area and follow the marked trail for 1500 metres to the waterfall. It's a relatively easy trail which is mainly level but watch out for the tree roots. It is a beautiful area and the water is crystal clear. You can take a dip in the river or the pool at the bottom of the falls but the water was quite cold when we were there in April. The ferns, strangler figs and moss are plentiful. There are picnic facilities and pit toilets back at the car park. It's easy to spend half a day driving there and back and including time for the walk.
