Are the kids starting to get tired of the ordinary trampoline? But have they heard of the kind where you can jump against the walls? That's something new! If you're in a group of eight people, you can also play "Völkerball", a type of dodge ball on trampolines. Additionally, there's a boulder wall, laser tag, a high-wire park, tennis, badminton, squash, a football field and - for groups with a reservation - even bubble soccer, where you climb into giant balls and try to bring down your opponent.
