Best kept secret, this walk. I didn't find it difficult, heavy going on the beach if the tide is high, so would pay to check that out before you leave and make sure you are walking Discovery Bay on a low tide.
Great diversity, you walk through forests, along a magnificent river, (which you can swim in), along a wild beach and then transverse spectacular cliffs. The walk had very few hikers, except the odd school group, or day walkers near settlements. Heaps of wildlife, both on land, in the air and in the sea! The camps are simple, (which is a welcome change from all the 'fancy' walks around these days), a shelter, open fire pit, tables and benches, rainwater and bush toilet.
The track can be accessed at many points, so is a great walk to be able to do in sections. Highly recommend.
