Having taken the family there 2 years ago, I can say it was great for the little'uns to run around for hours. I thought at the time there was not many photo opportunities. However this could have been due to having to chase the little'uns everywhere, and being there in the middle of the day 10 to 4. Could be great at sunrise and sunset however.
If Melville Caves are the destination the weekend before Easter then I will have to pass. It will be the weekend before school holidays and I'm off to Mildura for Easter and the first week of school holidays. On the other hand if we head out somewhere closer to town then I reckon I can make it.
Like other posts, I cannot think of an urban adventure location. Dohh!
