An enormous bungee jump platform has been set up near the I’m A Celebrity site in north Wales.

Ant and Dec hosted the ITV series. Viewers were able to see the contestants face their first fearsome challenge. This could include launching from heights. 

This structure was constructed at Alexandra Quarry in Penyffridd, outside Caernarfon.

Workmen were dressed in high-vis jackets as they prepared for the November 21 launch event. 

Every show begins with a bold challenge. Previous years have seen contestants leap out of helicopters or abseil down steep cliff sides. 

MailOnline reached out to me about I’m A Celebrity.  

Woah! Viewers of the ITV show hosted by Ant and Dec have been given a glimpse of the contestants' first terrifying challenge which could involve launching themselves from a height

Woah! Watchers on Ant and Dec’s ITV Show have seen a preview of their first frightening challenge. It could be launching from heights.

This is after celebs moved into Cottages in Angelsey, near Gwrych Castle. It was the ITV’s second-year running location.  

Luxury holiday homes have been built for stars with high ceilings, weather-proof windows and sliding glass doors that frame beautiful views.

Produces will create a bubble to protect the stars’ faces. This will avoid any disputes over vaccines, and ensure that they are safe when in quarantine.

MailOnline previously heard from a spokesperson for the show that celebrities would go through a two-week quarantine and be subject to regular testing before they enter the castle. Once inside, the bubble, which will last them the length of the show, will form. 

I’m A Celebrity asked celebrities last year to use proximity monitors that flashed or buzzed when they were too close.

Bosses reduced the number of production staff and set cameras up on site so that cameramen wouldn’t need to travel on set. 

Stars: Included in the line up are EastEnders' Adam Woodyatt, Corrie's Simon Gregson and GMB's Richard Madeley (pictured)

Date: The stars will all be heading to Gwrych Castle in north Wales for series 21 which starts on November 21 (Frankie Bridge is pictured)

Stars: The line-up includes EastEnders’ Adam Woodyatt and Corrie’s Simon Gregson. GMB’s Richard Madeley is also included (left), Matty Lee, an Olympic diver, Frankie Bridge (right).

Kadeena cox will play paralympian, while Loose Women’s star Frankie Bridge (presenter) and Louise Minchin (paralympian) will also be there.

The remaining members of the lineup are Arlene Phillips and David Ginola as well as Kadeena Cx, Danny Miller, Frankie Bridge and Snoochie Shy.

Ant and Dec, the hosts of this site will welcome new stars in the following days. This is in response to the pandemic which has seen the event take place in Wales instead of Australia.

Gwrych Castle renovations are close to completion in preparation for the launch of the new series later this month.  

On Saturday, two towers were constructed on the grounds at the Castle in North Wales.

These towers had eight points on their sides and were enclosed by scaffolding.

Several crew members were seen climbing up the staircase of the castle to finish the job.

Behind the castle, a large marquee in white was also set up for production purposes. 

It was recently revealed that famous faces entering this year’s I’m A Celebrity must reveal how much alcohol they drink on a weekly basis and their regular medication in order to prevent any meltdowns in camp.  

ITV bosses can only make a decision on whether a contestant will be suitable for the show if they have all of the forms.

It is believed that the intimacies were done in an effort to avoid Gemma Collins meltdowns.  

A source told The Sun: ‘The questionnaires are very detailed and for good reason. Producers need to determine if the celebrity is mentally and physically fit for the task ahead.

“It’s an entertainment program and it’s not worth signing someone up who can’t do any tasks.

According to the paper, campmates should also provide details about any medical conditions such as sleepwalking, night terrors or vertigo, as well as their permission for medical staff to reach out to them.
