Terrain roller coasters are roller coasters which, as their name suggests, take advantage of the (usually) natural undulations of the land upon which they are built. Such rides may often weave through forests, and some may even dive down cliffs. Because they tend to stay close to the ground, they require less supports and thus are usually cheaper than the same coaster on flat ground.
