• Book an hourly slot online before you go: main-floor entry starts on the hour after a short safety briefing, while Kids Jump needs no booking
• Anti-slip socks and sports clothes are required on the trampolines, and the desk sells socks for 60 Kč if you forget them
• An adult comes along for kids under 15, and a parent who doesn't jump doesn't pay

JumpPark Letňany fills an industrial hall with rows of trampolines, a foam pit, ninja courses, a warped wall, monkey bars, a battle beam and a dodgeball court. Children under 110 cm stay in Kids Jump, a separate zone with small trampolines and building blocks.

The main floor suits older kids and teens. Flips and somersaults are only allowed with a coach.
