Go to Joyridin', select the Snow level, and the rally car. From the start, go to the ice then follow the river. When you reach the split, take the right side. When you reach the dock before the bridge, make top speed. When you reach the steep wall you will see two dark stripes on the sides. Go towards the left one and drive up the hill about three feet away from the dark stripe. When you get to the top and go airborne, level out the car and go to the right at the top. Follow up the hill to get to the highest point of the level.
