Forbes, Free spot down to the left before the bridge if heading north. Can't camp in the first spot where the toilets and dump point are, you must go further down to the next park, quite a bit of room and plenty of pelicans to admire.
Lake Cargellico, there are 2 camps down by the lake, I stayed at Frogs Hollow, no facilities but very picturesque.
Griffith, a great free parking area along the canal, has toilets and dump point, park next to the park under the willows., very pretty.
