I found a cool tunnel that at the end, you fly through and out of a waterfall. First start the game in Joy Rider,(2 player). Play in the Forest. When you start, in front of you is a river. Go right, and follow the river until you get to a waterfall. When you are looking directly at the waterfall, you will see a path that leeds up to the top of the waterfall. Go up that path. When you get to the top, keep following the path until you get to the end of what looks like a forest like half pipe. To your right will be 2 bridges. Go to the second one, the one that does not have a roof over it. Drive across the bridge and right when you get across, in the top left hand part of your screen, there will be a pretty good sized hill. On the other side of ther hill, which is not the far at all, there is the tunnel. Go into it. You will start to go down, then up, and make a few turns. But at the end, is where you FLY OF A WATERFALL!!!!( a neat little trick is to have 2 players, and one of them watches the front of the waterfall while the other flies out, and you can see a car suddenly shoot out of the waterfall, it is pretty cool.
