Avalanche was a steel bobsled roller coaster at Kings Dominion in Doswell, Virginia, built by German manufacturer Mack Rides and opened to the public on March 26, 1988. It was one of only a handful of Mack bobsled coasters ever built and the only one operating in the United States, sending its trains down a trackless steel channel much like a real bobsled run, with cars styled after Olympic bobsled teams from nations including the United States, Germany, Switzerland, Canada, and France.
Riders reached speeds up to 41 mph without a single inversion, relying on high banked curves and sweeping drops rather than loops for its thrills. The ride sat closed during 2020 and 2021 amid the pandemic and construction of the neighboring Tumbili coaster, then returned for the 2022 season repainted in earthy orange tones with new crocodile-themed cars to match the park’s Jungle X-Pedition area — and was renamed Reptilian, the name it still runs under today.

The Ride Experience
Unlike most steel coasters, Avalanche’s three trains of seven cars each ran along open half-pipe channels rather than fixed rails, letting the cars slide freely from side to side on turns just as a real bobsled would. Each train carried 14 riders, two per row, and climbed a chain lift hill before descending into a series of banked curves and drops that built up speed instead of relying on inversions.
The Olympic bobsled theming carried through to the queue and station, reinforcing the winter-sports identity that gave the ride its name. That theming, along with the coaster’s white color scheme, remained largely unchanged for over three decades until the 2022 refurbishment.
From Avalanche to Reptilian
Kings Dominion announced in January 2022 that Avalanche would reopen as Reptilian, part of a broader push to add the Jungle X-Pedition themed area near the ride. The bobsled cars were repainted and reshaped to resemble crocodiles, and the structure itself was given new earth-toned paint in place of its original white finish.
Mechanically, the coaster is unchanged from its Avalanche days — the same Mack Rides bobsled trains, layout, and 41 mph top speed remain, only the name and theme were retired.
