The most difficult stunt in figure skating is generally considered the quadruple Axel. It’s especially hard because the Axel takes off from a forward edge, so a quad version requires more than four full rotations in the air before landing.

Why it is so hard

  • The Axel already has an extra half-rotation built in compared with other jumps.
  • A quadruple Axel pushes that to the extreme, demanding enormous height, speed, timing, and control.
  • It is widely described as the hardest jump in the sport, even among elite skaters.

Other very difficult moves

  • Triple Axel: historically one of the toughest standard jumps.
  • Quadruple jumps: extremely demanding and a major technical benchmark in men’s skating.
  • In pairs skating, some banned or risky moves like backflips and unusual lifts are also very dangerous, though they are not usually called the hardest “stunt” in the same way as the quad Axel.

Plain answer

If you mean the hardest jump, it’s the quad Axel. If you mean the hardest overall trick, many skaters and fans still point to the quad Axel as the toughest single element in figure skating.

TL;DR: The quadruple Axel is widely regarded as the hardest stunt in figure skating.
