We did the Extreme Quad Adventure and loved every jaw-rattling, kidney-bruising minute of it. Saw echidnas and kangaroos and loads of countryside while bouncing along the clear and well-maintained tracks. A little bit of everything on this run. If you're going to do it though I recommend you take a jacket with zippered pockets because anything in open pockets will quickly fly out. I only wish I'd been able to get some pictures of this.
Long story short - What a great time!!
