La Vibora, Steel bobsled roller coaster in Arlington, United States

La Vibora is a steel bobsled roller coaster whose cars run through a winding half-pipe trough rather than on tubular rails. The tube is painted in broad alternating bands of black, cream-yellow and dark red, carried on a lattice of narrow grey-beige vertical and diagonal beams. A tall support tower with a red and white striped top stands beside the track.

The coaster debuted in 1984 as Sarajevo Bobsleds at Six Flags Magic Mountain in California. It relocated to Texas in 1986 and operated there until November 2024.

La Vibora is Spanish for "The Viper", a name given when the ride was repainted to match the Spain section of Six Flags Over Texas. The trains are the original bobsleds from the Bob ride at Efteling in the Netherlands. The coaster closed without announcement during the 2024 season.

Riders must be at least 42 inches tall and six passengers sit per car with lap restraints for safety. Wearing secure footwear and securing loose items is important since the ride features multiple rapid directional changes.

La Vibora's cars were the original bobsleds from the Bob track at Efteling in the Netherlands, transferred to this ride. The trough is a half-pipe, not tubular rails, so the vehicles slide rather than lock onto a track. With La Vibora's 2024 closure, no Intamin Swiss Bob model remains operating anywhere.
