Boomerang, Steel roller coaster in Bellewaerde, Belgium.

Boomerang is a steel shuttle roller coaster at Bellewaerde, built by Vekoma in 1984. Its yellow track forms a twisting loop held up by dark blue columns, and the train runs forward through a loop and a cobra roll, then repeats the course backward. The track covers a footprint of 88 by 30 metres.

Boomerang opened at Bellewaerde in 1984, built by Vekoma as the second Boomerang model constructed. The first, assembled in Rafaela Padilla, Mexico, in 1982, was delayed by technical faults, so Bellewaerde's ride was the first Boomerang opened to the public. Its original white track and dark green supports were repainted yellow with navy blue supports for the 1997 season, when a new Vekoma train in matching colours entered service.

During Halloween the ride is renamed on park maps and signage: from 2012 to 2014 it appeared as Zoo'merang for Halloween ZoorRror, and in 2015 and 2016 as El Bumeran de los Muertos for Halloween Fiësta Mortal. Smoke, laser and extra sound effects are added in the station. A Vivelle Dop Extra Strong Fixation advert was filmed on the ride.

The train seats 28 riders in seven cars of four, and the ride handles about 630 people per hour. It reaches 5.2 g and turns riders through six inversions, a loop and a cobra roll, once forward and once backward. The layout covers a footprint of 88 by 30 metres. Loose items should be secured before boarding.

Riders experience the same loops and turns twice in succession, yet each ride feels entirely different. On the backward second journey, the experience gains a new dimension since riders cannot see the track ahead of them.
