I checked out the Badger Caravan Parks Reports site, but they are looking for an updated report on the park.
I then did a search in this forum and there was one very favourable report made back in July 2013. Sounds like a great park. Do a search yourself, just click on "search" in the very top blue line and type in "Alva Beach Caravan Park" and up it will come.
If it was me I would book in for a couple of days and if it wasn't up to standard, move on.
If your do end up there post a report on the Badger C/V Report site.
Thanks guys, thinking of calling in there on our way back down.
We went to Alva Beach for a drive last night.
Had a lovely walk on the beach.
Best of all the fish were literally jumping out of the water.
