Small DEC campsite with only 6 bays. 

Near Barrabup Pool, about 10km from Nannup. 
Turn off Mowen Road.

Very clean and well cared for.
BYO water and firewood. 
Long drop toilets.

Geared more towards tent campers though you could get a small caravan or camper trailer in a couple of the bays.  Bay 2 has a raised section where we pitched a 6man tent with 2 metre vestibule.  Bay 5 appeared to be more of a group site with 2 picnic tables and larger fire pit.

The evening saw a very brazen visitor (possum) try to nick our food out of zipped up bags while we were sitting less than 6 feet away with a fire burning.

The pool is supposed to have fish in it... bream I think
