‘ZipZag Rides was born out of the successful engineering consultancy, Castree, that has a specialism in amusement technology. Before founding Castree in 2010, my career was with several consulting engineering practises. The work included tension and cable roof structures and leisure devices of all sizes, ranging from reverse bungees, roller coasters and up to the London Eye. It is a great privilege to be surrounded by the enthusiastic team, creating a ride we are all passionate about. Welcome to ZipZag!’
