A TEENAGE boy is dead after falling off a frozen water slide at Mount Olympus Water and Theme Park in the US.

Police say three juveniles, Addison Williams, his brother and a friend, climbed a fence and entered a restricted area and climbed one of the water slides.

Sixteen-year-old Williams used a plastic snow saucer to slide down the slide but halfway down he got caught in snow. When he was trying to free himself, he fell 11 metres onto another slide.

The outdoor water park in Wisconsin is closed for the season.

Lake Delton Police Chief Daniel Hardman said the two other boys realised the dangers of going down the partially frozen slide and warned Williams not to do it.

But he made an attempt anyway.

Hardman said rescuers were dispatched around 10:20pm on Wednesday and they tried to resuscitate the teen, but he was pronounced dead at the scene.

Williams’ family was staying at the resort, visiting from Florida. They were there to see snow for the first time.

The Sauk County Medical Examiner’s Office is helping with the investigation.

The theme park offered its sympathies to the family, but said that’s why they have a padlocked fence around the park — because it’s not safe in winter months.

A cousin of the teen has set up a GoFundMe account to help cover the teen’s funeral expenses and costs to get him back to Florida.
