Vildeberg

Roller coasters can be found in all corners of the world*, and if you're ever in the middle of nowhere in rural Sweden, you might come across a gem like no other.

In 1986, coaster manufacturer Arrow Dynamics teamed up with furniture manufacturer IKEA to build a terrain coaster that was both exciting and easy to assemble. As is the case with all IKEA furniture, the ride was given a European-sounding name in capital letters and blueprints explaining how to put it together. VILDEBERG was the chosen name, which translates roughly to "wild mountain" in Swedish, and upon its opening, the name was stylized so that only the first letter was capitalized, as is custom for most roller coasters that aren't acronyms or random assortments of letters and numbers.

Built on and within a small hill near the base of the Scandes, Vildeberg has attracted crowds since its opening, and has remained the number one attraction in the mountain range among people who want to visit the mountain range but don't like mountain climbing. Coaster enthusiasts are especially fond of it because it's truly one of a kind. Instead of building it above the terrain, Vildeberg is built with the terrain, with some sections of track standing a mere six inches above the ground. These sections are to simulate riders riding a snake in the grass, which adds a level of suspense that very few coasters have ever been able to produce.

In addition to its beautiful setting with rugged terrain, dense and diverse foliage, and stunning architecture, Vildeberg's most notable quality is its unpredictable and unorthodox layout. Following a long, tall lift hill, riders fall from a short curved drop into the first inversion--a corkscrew--and immediately plunge from the second inversion--a sidewinder--into an underground tunnel. Following a quick jolt upon exiting the tunnel, the train curves back up to the top of the hill, whereupon it slithers around curves, giving riders goosebumps, until it finds its way to the brake run building. From there, it dives off the cliff into a sharp, banked curve just above the water, jumps through some hills, and twists through some curves before running into its third inversion--a classic vertical loop--and then immediately into the fourth one--a sidewinder built into a tower. After a few more winding drops, sharp curves, and one final underground tunnel, the slippery beast finally finds its way home.
But nobody rides Vildeberg just once**.

*This implies that the world is cube-shaped. Recent studies show that this is not correct, though the main point that roller coasters can be found anywhere is still valid.
**Some people actually do ride Vildeberg just once, but the general idea is that it's such a good roller coaster that most people want to ride it a second time.
