Welcome back RYAINS
We usually go away in our Campertrailer every Xmas with our 3 kids (17,15 & 12) for a week starting from boxing day and the last two years we have been to these two spots and would love to go back to both again. You might have trouble trying to get a spot though as they fill up pretty quick from about May onwards and you usually have to stay 7 nights. The beach spots (if you are looking to go) will be even harder to get.
We loved SWAN HILL. The big 4 we stayed in had pedal cart races for the kids with prizes, movie nights, tennis court, pool our kids loved it there and the town was lovely. The town is on the Murray River and our girls caught two fish from fishing on the banks and hubby wished he bought the boat. Pioneer museum was also great. Paddle steamer ride was also great fun. We want to go back again. http://swan-hill-pioneer-city-tourist-park.vic.big4.com.au/photo-gallery.aspxhttp://www.pioneersettlement.com.au/
DENILIQUIN was another big 4 we stayed in and we had a powered site right on the river. The only critisism would be that the powered and camping sites at the back of the park would have been really hot, so I would only camp on a riverfront site there. Lovely park with big outdoor movie screen that they moved around the park every second night and also had movies in the function room every day. The town was also nice...not as much to do as in Swan Hill but nice. The park also had a pool,tennis court, jumping pillow.http://deniliquin-paringa-holiday-park.nsw.big4.com.au/photo-gallery.aspx
Two of our favourites so far.
