When I saw this list I knew your home park would come to mind. It's got three that definitely use the terrain well. Here's the ones that come to mind for me: Dollywood: Lighting Rod (probably the best terrain use of any coaster), Tennessee Tornado, Wild Eagle (that hill top really does a lot) SDC: All of them. Best park for terrain use Lake Compounce: Boulder Dash. Maybe the first coaster that comes to mind when you think of just utilizing the terrain BGW: Apollo's Chariot and Alpengeist do a surprisingly good job of utilizing the terrain despite being such large structures. Also Verbolten Kings Island: I think The Bat is the real winner. The Beast feels like a terrain coaster but I think that The Bat actually does more with its topography Fiesta Texas: Iron Rattler and Superman Krypton Coaster use that wall very well making those rides feel very different from similar models Magic Mountain: Tatsu, Revolution and Ninja really use that mountain to full effect Holiday World: their big three woodies manage to take full advantage of this small bit of varied terrain. It's pretty impressive because even 5 minutes from the park in any direction you'll find typical flat farmland of the midwest. Honorable Mention: Arrow Mine Trains. Initially out of necessity but eventually out of style, these were very strategic in terrain use. They're all unique for that reason. And some do an especially good job of terrain use. I think of Road Runner, Trail Blazer, Thunderation, Goldrusher, Adventure Xpress, and even to some extent Runaway Mine Train.
New flash, Verbolten isn't a terrain coaster, it's a glorified box coaster that grafted Big Bad Wolf's ending to it. Don't call that thing a terrain coaster, only the last portion of the ride is a terrain coaster. It's 95% box coaster and 5% terrain coaster.
Outlaw Run is an incredible night ride, especially when it's 34 degrees! It's up there with Voyage among the best. Voyage & Prowler are 2 terrain coasters that are not so obvious that they use the terrain, but the terrain usage adds power to the elements and pacing.
So many coasters come to mind instantly like nitro the beast the voyage outlaw run lightning rod kumba boulder dash Arrow mine trains and maybe even cheetah hunt
I am surprised not to see The Voyage at Holiday World on the list. Wouldn't that be considered a terrain coaster with it going out into the woods and back?
