Please do not stay here. IF TENTING It is $40 a night then extra $13 for EVERY EXTRA PERSON, even though you are paying for a 10m by 10m site with power. You will be 2-3m from all nearest neighbours. The toilets are more than unhygenic, the showers barely let water out and the shower heads constantly fall, hitting you on the head.
The camper kitchen is disgusting and the whole sink and bench and bbq is permanently covered in ants. (No matter how much I tried to clean it)
There are way too many privately owned caravans meaning the site is always full.
I also went camping to be in the bush, surrounded by nature instead I was charged $60 a night to tent on a bit of grass on the side of the main road to Myalup Beach, I didnt sleep 1 night of the 3 nights I stayed because of the amount of truck deliveries and car traffic to the beach during the night for late fishers.
I also was woken up at 4.30am every morning by a group of men that sat on the side of the road (2m from my tent) yelling til 8.30am when the shop opens.
I could write alot more but I really hope you choose to stay at Preston Beach or Binningyup instead as this place is impossible to sleep and has more traffic than my house in Perth.
 

Approximate cost: $60
