Big Loop, Steel roller coaster in Heide Park, Soltau, Germany

Big Loop is a Vekoma steel roller coaster at Heide Park in Soltau, opened in 1983. Its 706 m circuit includes two vertical loops and a double corkscrew, with a 30 m chain lift and a top speed of about 60 km/h through the loops.

The ride opened in 1983 as the park's first roller coaster, originally using trains made by Arrow Dynamics. A redesign in 2010 replaced these with newer Vekoma trains, updating its operation.

The layout was copied almost one-to-one from Dragon Fyre at Canada's Wonderland. Its straight sections, unusual for a Vekoma Double Loop Corkscrew, were added to fit a block brake after the corkscrews, allowing three-train operation on the short track. The brake was later removed because staff struggled to dispatch trains in time.

Each train has six cars arranged in two rows, holding 24 passengers per ride. The ride processes around 1200 people per hour and reaches a top speed of 63 kilometers per hour.

The ride starts with a chain lift hill climbing 30 meters before the trains descend into the loops. After the two loops, a mid-course brake section slows the trains before they complete a final helix turn.
