The freestyle ski halfpipe takes place in a half-cylinder-shaped course typically dug into the side of a snow-packed mountain.

Acquiring high rates of speed before reaching the course, freestyle skiers drop into the halfpipe before ramping up over the top of the pipe while performing aerial spins and grabs.

Skiers then fall back down into the course before ramping up the opposite side.

Female competitors can reach heights of 15 metres above the ground before dropping back into the curvature of the halfpipe.

The previous action is repeated a half-dozen times while judges look on and rate competitors based on how well they perform a list of aerial tricks and the difficulty of those maneuvers.
