This is a very popular spot with fishermen and tourist alike, some stay at the Blowholes Camp and some at Quobba Station.

I stayed at Quobba Station, unpowered site for me was $13.50.   Included showers and toilets.   Best to take own drinking water, some tank water at the Station though for drinking.

I was not all that keen on the Blowhole Camp, needed to be self contained also. 

It was not very rough when I was there so the blowholes were not very active but still ok.   Bitumen road into the blowholes and 7kms of dirt road to Quobba station.  HMAS Sydney memorial also on Quobba Station on the way in (this was where the German survivors landed and some other items from both ships were washed ashore, and is not to be confused with the Geraldton memorial.
