This is a beautiful little walk, it is very short and great for kids with young families, just take them there put them in a wetsuit and let them play in the little river and the sand.
This is also one of the best places for an overnight camp on the coast with only a small walk in so it is a great walk to get you into overnight hiking. You can book using the National Parks website here.
The area has 7 campsites, a clean composting toilet, a free BBQ and very unusual for national parks, bins.
