The Dubbo City Caravan Park is next to the river and has a nice quiet feel. Colorful kids play equipment (though not under cover). It has the best pool of any caravan park in Dubbo. Last time I checked it was $20 for a powered site, plus $4 per child. Ph no is 02 6882 4820. It’s on the West Side of the Macquarie River between the two main bridges.
I’ve had two families who have reported having their cars broken into while staying here. It has a very big fence around it. But apart from that it’s a very nice park and cheap rates.
