• Book a jump time online ahead: sessions start on the hour and half hour, and you need to arrive 15 minutes early for check-in and the safety film
• Grip socks required on the trampolines, with no bare feet or shoes; they cost 49 kr, are reusable, and toddlers jumping free still need a pair
• Busiest on weekends and holidays between 10am and 2pm, so a weekday afternoon is calmer

YOUMP's biggest trampoline park covers 4,200 square meters with trampolines from wall to wall. Beyond the open FreeJump area there's a ninja course, a big airbag, dodgeball, an AirTrack tumbling strip, a slackline and a separate toddler and baby area. No experience is needed, and kids jump at their own level.

The park also runs birthday parties, trampoline classes, holiday camps and evening discos.
