A helix is a banked upwards or downwards spiral, generally exceeding 360°. The helix section of a roller coaster closely resembles a coil spring in the way that it spirals up or down. A helix can be clockwise or anti-clockwise. The mirror image of an anti-clockwise helix is clockwise and vice versa.
