We have been staying at Orleans Bay Caravan Park for years now, and absolutely love it. We always endeavour to go at an off peak time, as we know it's booked to capacity at peak times and that will affect your peace and quiet / bathroom wait times etc (but that's to be expected like any other place).
The owners are fantastic and remember us each time we go there. We love taking our four wheel drive on the beach (yes, you're allowed to!) it's great fun exploring the beaches. We also take our quad bike and those are allowed on the beaches also. Great fishing (not giving away our fave fishing spot though - you'll have to discover it for yourself!)
The thing that first attracted us to Orleans Bay Caravan Park was the fact that they allow dogs in the park - our dog is our baby and we are so glad she gets to come with us! She just loves going to Orleans Bay.
The beaches and scenery are the prettiest I have ever seen, I highly recommend this place to any traveller - provided it's not at peak times.
