This is a 'must visit' if you're in Mildura. For adults there's lots of interesting information on gems, they make their own jewelry there and there's presentations plus the staff are very friendly and helpful. For kids (and adults) there's a cave with real gems in it to walk through and enjoy. And then out the back there is this MASSIVE maze that will honestly take you quite a while to get through - and entry into it is only a couple of bucks. Real fun, and if you're wanting to buy something special for that someone special you'll find it here too.
