Valkyria is a 750 m long dive coaster from  Bolliger & Mabillard which opened at Liseberg in 2018. After the lift hill and short panorama tour at the top, you hang out for few second over the large drop, before diving 50m down. Since the track is nearly vertical during the dive, you experience a nearly free fall.

After about 1 minute, you can also see a "zero-g-roll" where you are nearly weightless, while rotating around your heartline.
